US Date Format and ISO 8601

qquito - 15 Feb 2010 02:22 GMT
Hello, Everyone:

In the US, the format to express a date is to put the MONTH in the
first place, then the DATE and finally the YEAR. In Europe, however,
the order of MONTH and DATE are reversed. The two formats can cause
confusions when written all-numerically, such as 02/04/2010.

In some other parts of the world, the YEAR comes the first, and then
the MONTH and then the DATE. Maybe computer scientists and
mathematicians first realized the advantages of this logical, big-
endian format, and as earl as 1988, the ISO 8601, an international
standard covering the exchange of date and time-related data, was
published (http://en.wikipedia.org/wiki/ISO8601). According to this
standard, the date February 14, 2010, for instance, is written as
2010-02-14, all-numeric. I suppose this can be understood correctly by
people all over the world without any further explanation.

In this computer age, this big-endian, all-numeric format has many
advantages. For instance, when you write diaries/journals in your
computer and name each file by the date using the above format, all
the files list chronologically.

In science, many data are closely related to time and therefore have
been named by date (and/or time as well). And in the past, the 3-
letter month names (jan, feb, etc.) and/or the all-numeric format [MM]-
[DD]-[YYYY] have been used. And this has caused considerable,
althougth resolvable, inconvenience in managing the data files.

After all, all time-related records are organized according to YEAR,
MONTH and DATE in that order, and we locate a historical material,
such as The New York Times on 1944-06-06, we locate it in that order.

I wish that we start to use the ISO 8601 standard, i.e., the all-
numeric [YYYY]-[MM]-[DD] format in our daily life, in calendars,
newspapers, magazines, TV, etc.. For now, we can at least use it in
our personal life for its convenience.

We in America put the month first because one generally says February 14th
2010.
so it gets written as 02/14/10.
That the Europeans do it wrong is their problem. ;-)

Many people say "14th of February" though, at least here in Australia.

For many Americans, "the fourth of July" means Independence Day,
whereas "July 4" merely names the date that it happens to fall on.
There is even a joke:  "Do they have a fourth of July in Canada?"
"Yes, it is the day after the third."

They have July Fourth, they just celebrate it three days early. :-)

If I'm not mistaken, "Independence Day" is the name of the holiday.  
"The fourth of July" and "July 4th" are informal ways of referring to
it.

I agree that "the fourth of July" usually refers to the holiday and
"July 4th" to the date, but I don't agree that it is 100% that way.

Many scientific publications in the U.S. specify dd Month yyyy (with
the month spelled out), and that is what I use in snailmail
correspondence (of which there is not much these days).  For internal
use in filenames etc., I use ddmmyy, where mm is ja fe mr ap my jn jl
se oc nv de, and where the century begins on 01ja37 (my contribution
to the Y2K problem -- if I live to be 100, I'll be sorry).  I have
written programs to do arithmetic on dates in that format.

I used to use a format for files similar to yours with the month
spelled out  in 3 letters. However, as the number of files
accumulates, the sorting and managing become a nightmare.  Now I use
the format YYYY-MM-DD, YYYY_MM_DD or YYYYMMDD where the MONTH is
numeric, and the MONTH and DATE use leading zeros if they are 1-digit.

More seriously, is there any evidence that one is more common than other
in the spoken language, and is the usage regional? In the UK I believe
it is normal to put the date before the month.

In these two random examples, *date* is misused for *day* (in my opinion
and usage).

Yes, I know, some dictionaries confusingly define _date_ also as "the
*day* of the month," but I would never use "date" to mean "day."

These are *dates*:  15 April 2010, 2/4/02, 8.IV.1936, etc.

These are *days* (of the month):  third, 10, 15th, 31st, etc.

Nota bene:  The "dd" or "DD" means "day," not "date."  MMDDYYYY
(month-DAY-year) is a "date."

So qquito's

    the format to express a date is to put the MONTH in the first
    place, then the DATE and finally the YEAR. In Europe, however,
    the order of MONTH and DATE are reversed.

should be:

I'm well acquainted with 8601 from the two years I spent preparing a suite of
software for Y2K (internal dates were stored as binary "number of days since a
standard zero point" but there were all those conversions to and from various
external forms)....

The greatest advantage of the ISO version is that entries will sort into proper
chronological order without any special treatment that depends on the fact that
they're dates....

For my personal use, I use a modified format that omits the delimiters...my
binder full of recorded broadcasts from Taiwan Radio has filenames in the form
"YYMMDD_HHMM.mp3" up until 2008, and "YYMMDD_HH00 MM SS.SSSSS.mp3" thereafter
(the extraneous digits because I'm now letting the editing software name the
individual files and the editing software doesn't allow any truncation)...I
don't need four-digit years because I didn't start collecting them until after
the turn of the century....r

I think that's a close second to this one:

When you read 02.11.2010 you can't be sure whether it's 11 February
or 2 November.  When you read 2010-02-11 there is no doubt.

I've been using ISO format consistently for about a decade now, and
no one has ever questioned it or (as far as I'm aware) misinterpreted
it.

(My guess.)

I suspect that once the year is placed in front, few people would
expect to see the day next, before the month.

11-February-2010 and February-11-2010, when converted to numerals,
are confusable, because both are commonly encountered sequences.  

Putting the year first is alien to both, so 2010-February-11 just
seems a bit more likely than 2010-11-February, even when converted
to numerals.

I don't find that too convincing. The old technique that I used in my
schooldays of using lower case Roman for the month is more effective
tho' probably, it might add complications to computer recognition.

I assumed that of course people would understand that you go from the
largest unit to the smallest. And the first number is obviously the
year, so the next must be the month and the last the day. Nice, simple,
sorts nicely, and no one's had trouble with it since I started using
Year-Month-Day at work.

At least, no one's told me they find it confusing. I find trying to
guess whether any given person is using the American or British system
confusing, especially since so many people use only numbers, and don't
put a handy note ("Day-Month-Year" or "Month-Day-Year)next to the numbers.

Not least of which is that it introduces a variable-length component...a
competing standard I've seen would render the above example as "11feb2010",
which makes it even clearer to anyone who's still uncertain that the string *is*
in fact a date, while at the same time rendering delimiters unnecessary....

It's a bitch for sorting, though....r

I think you're right that it's more likely.

I tend to use the form "11 Feb 2010" (with the three-letter month,
which I hope makes it unambiguous) when writing a check or in contexts
mainly for human consumption, and ISO format elsewhere.

I have been using the ISO format YYYY-MM-DD in writing checks for a
few years, and there has not been any confusion. And today is
2010-02-15.

So do ours, now. I'd forgotten that. Well, they come with spaces for you

Exactly why is there no doubt? Until I was exposed to Americans, I had
no doubt that 02.11.2010 meant the second of November. I now have no
reason to believe that somebody somewhere won't use 2010-02-11 for the
second of November too.

Perhaps you will claim that logic tells you that year-month-day is a
progression from larger to smaller, but clearly logic does not tell
Americans that day-month-year follows a similar, if different, pattern.

To my mind, our only hope today is use letters for the months.

Because Americans have never, ever, used a year-first format in the
past, and only true geeks do so now.  If you see an ISO 8601 date
written by an American, you know that the writer was someone who
actually (a) was familiar with, and (b) cared about using, that
format.

It used to be that the standard German and Scandinavian format,
dd.mm.(yy)yy, was unambiguous, too, but then US-based graphic
designers decided that the punctuation of dates was subject to their
whims and started writing dates mm.dd.(yy)yy instead of the standard
mm/dd/(yy)yy.  (The Northern European format actually made sense,
because in those languages, a trailing dot after a numeral was -- like
the use of Roman numerals -- an indication of an ordinal rather than a
cardinal, so you had a date "the ddth of the mmth of (the year)
(yy)yy".)  I doubt (although my intuition in these areas is often
wrong) that Frank Stanton would have tolerated such a designer in his
employ.

So do I.  I have a Perl script (available if anyone cares) that uses
jhead to generate filenames based on the Exif timestamp.

Consequently it drives me nuts when I'm merging holiday photos from
other family members' cameras in with mine and someone's clock isn't
set.

And sets the modifation timestamp on the file to match?  That's what

That's why I have another Perl script that adjusts the timestamps (and
file name) by a set amount.  Also fixes "Damn.  Forgot to adjust the
clock when we went on (or came back from) vacation."

Now you're just showing off.  ;-) No, I'm happy with just the

The jhead program itself does that.

   -ta<+|-><timediff> Adjust time stored in the Exif header by h:mm
   backwards or forwards.  Useful when having taken pictures with the

Maybe just a little.  The reason that I can't just use the filenames
is that the naming scheme I use also encodes the camera used (mine or
my son's) and the sequence number according to the camera), with those
two elements at the beginning (because the sequence number is the
easiest way to refer to the picture and it would often be truncated
out in narrow fields).  So it wouldn't sort correctly with an
alphabetic sort.

I use Adobe Photoshop Elements to organise photos. It doesn't matter
what the pathname is, they're displayed chronologically by EXIF time
(or, failing that, file time).

Not only that, but APE can adjust the time of groups of photos to take
care of the problem you describe. Working out exactly how *much* to
adjust them by isn't always easy, though.

An indexing program such as APE also allows me to retrieve photos based
on tags indicating the person(s), place, event, etc.

I'm reading this thread with interest because I am so "in" to
photography, but I really can't understand the comments about
precision in file naming.

Some of my photography is the usual family pix stuff, but the bulk of
it is in the hobby area ranging from candid "street" photography to
anything that looks like it would make a good composition.

For the family pix, year-month-date is sufficient in by-year folders.
The rest are stored in Adobe's Lightroom* program and retrieved by a
keyword system, but also named in the year-month-day format.  I have a
second Lightroom catalog for old family scans, and that one is
keyworded by subject(s) in the photo.  

I can't understand the need for knowing the exact time from the file
name.  (Although that is stored and viewable in the EXIF data of the
RAW original)

*A program that would handle Evan's need to know "Which camera?"
because it will sort by camera body and/or lens used.

I may have to take a look.  I'm currently using ACDSee, but it's far
from perfect.  I see that Photoshop Elements now claims to do face
recognition.  Do you know whether it does a decent job?

Somewhat more OT, but does anybody have a good solution for EXIF dates
for scans of things where you don't know the exact day, and possibly
can't get it closer than the year or even the decade?

> I can't understand the need for knowing the exact time from the file

It's not so much exact time as sequence when lots of pictures are
taken on the same day, especially when there's more than one event
(or event component) on a given day.  The sequence number does it for
one camera, but when there are multiple ones and only one of them has
its camera three hours off, it can cause problems.

The other reason I want to keep information in file names (as opposed
to hiding it in the EXIF data) is that several times I've run into
tools that have "helpfully" removed the EXIF information from
pictures or reset the date to the current date, and so it's useful to
be able to go backwards from the name to the date.

> *A program that would handle Evan's need to know "Which camera?"
> because it will sort by camera body and/or lens used.  

My problem's actually the other way.  I want to sort by time,
regardless of the camera used.  I should mention that I also want to
be able to have the sort include video taken on the cameras, which,
unfortunately, doesn't have EXIF info, so the name (and filesystem
date) is all I have.

I have Photoshop Elements Version 5.0, which is far from the most
current version.  The only reason I have it is because my daughter
uses it, and she sometimes has questions about editing technique and I
will do a project and send her screen shots of the steps.  I use
Photoshop CS4 for editing my own stuff.  I don't use the "Organizer"
since I use Adobe's "Lightroom" for that function.

EXIF data is captured in-camera.  Scanners don't capture it.  (You do
create EXIF data, but the date and time is the date and time of when
the scan is made.) There are programs that you can use to add or edit
EXIF data to digital images on your computer, but *you* have to know
what to add or to change.

The only reason to add EXIF data to a scanned image is if the file
name would be too long to contain all the data you want to record.

I guess I haven't worked on a project where this has been that
critical.  I put together one file of all of the photographs taken on
Thanksgiving* by my daughter, my son, and me; each with their own
camera.  I use a (free) program called FastStone** Image Viewer 4.0
that's an image viewer with other features - including bulk file
re-naming - and drag-and-drop the images into the sequence I want and
then re-name them (date and trailing number) so the trailing number
puts them permanently in the right order.  My sorting is by scene and
not necessarily by time.  

*We spent Thanksgiving in North Carolina with another family on their
farm, and there were other guests there and a lot of different
activities.

Exactly.  Not very useful for describing the photo.  (And some editing
software changes it to the date and time of the edit.)

The reason to add EXIF data (at least an EXIF date) is to make it play
nice with other photos in the collection when using photo organizer
software.  Unfortunately, the people who designed the format
apparently didn't think about the problem of not knowing the exact
time the photo was taken and require it to be specified down to the
second, and organizer software will report it as though everything
they're told to report is valid.

That may be the difference.  I'm not thinking about projects.  This is
for long-term browsable mass storage.  We print out a fraction, but
even that's typically in batches that require us to go back over the
last few months and pick out the ones we want to print.

The reason that the scan-date question is coming up now is that we
just had 5,000 old prints scanned, and I want to be able to merge them
into the same store.

It's important to distinguish that product from Photoshop *Elements*,
the only moderately cut-down version for a very cut-down price of about
$79.

I've used all three:  Elements, Photoshop (full versions), and
Lightroom.  That "moderately" is a "YMMV" thing.  Once you are
experienced in Photoshop (full version) or Lightroom, you are much
more than moderately restricted using Elements.

I recommend Elements for people who want to do basic and basic-plus
photo editing, but Elements is really for the snapshot shooter who
takes family and vacation photographs.  If you get serious about
photography and going beyond family/vacation shots, though, the extra
features of Photoshop and Lightroom start to be become essentials.

Without layer masks, channels, and LAB mode, I'd feel very restricted.

Last week I was out at Sanford Marina on Lake Monroe taking some
pictures and struck-up a conversation with a guy there.  He was asking
some questions about my camera and the programs I use to process the
images.  

He had a $100 point-and-shoot camera, and commented about how much
money I'd spent on my camera and my software.  He was down here in his
huge motor coach and towing a boat. He'll spend more money on upkeep
of just that boat in the next 12 months than I have invested in my
camera hobby.

That's the American Way, though.

I used the first version of APE to do face recognition, which is now
quite old. It didn't do a good job, but then I didn't expect it to,
given the nature of the pictures. I find that it's as quick for me to do
apply tags manually as it is to check and correct the results of
automatic tagging, so that's what I do. APE makes it easy. You can use
control-click and shift-click to select a bunch of pictures, and drag a
tag onto the group. Or you can control-click and shift-click to select a
bunch of tags, and drag them onto a picture. Or both at the same time
(multiple pictures, multiple tags, one drag). And you can navigate and
scale the album while you're selecting.

Of particular interest for navigation by date is the bar-chart across
the top of the screen showing the number of photos in each month/year.

Now that's a problem I haven't figured out.  Where do you get the time
of the video from?  The filesystem's datestamp of the file on the
camera's memory card?

I think I tried it that way at first and found that that meant that
under a thumbnail that would often be truncated so that all that was
displayed was (at most) the date for all the pictures, which made it
hard to say "I think number 121652 is the best of the group".

Exactly.  My script actually copies off the card and renames the file,
putting it into the right Year/Month directory.  So I have the cards
timestamp available.

Actually, I'd say that it did, for at least some kinds of
conversation, and that it's one of the reasons that the First
Amendment says

   Congress shall make no law ... abridging ... the right of the
   people peaceably to assemble

The way you prevented private conversations in those days was to
declare any gatherings (of any size, especially if held in secret) you
didn't like to be "unlawful assemblies".

I really recommend that (free) FastStone Viewer that I mentioned in an
earlier post for this type of sorting.  You can open a file, go
through full-screen views of each photograph using the arrow keys, tag
the ones that look good, and then view just the tagged photos.  You
can then put up two or more tagged photos side-by-side and remove the
tag from the least desirable.  Repeat until you've culled it down to
the best of the group. I do this and then copy the "keepers" into a
new file folder that I'll use to print from or to send out for prints.
Then I remove all tags.

I recently figured out that one of our cameras (as it happens, the
only one normally used for videos) produces two files on the card for
each video:

47M  MVI_1667.AVI
11K  MVI_1667.THM

and the second one is a thumbnail jpeg file with a full set of Exif
information, including the timestamp.  So I should be able to produce
a script that finds pairs of files by name and extension, and renames
both according to the Exif timestamp.  Thanks for the inspiration.

I upload in Bridge (part of Adobe Photoshop CS4), and Bridge assigns
the file number that way (except for the description).  From there I
view the files in the FastStone Image Viewer, delete the bad ones, and
re-number the files using the hyphens.  I find the hyphenated form

I just use the standard DCIM image numbers.  If I need to know exactly
when a photo was taken, it's right there in the EXIF data (and from
there it ends up in my index.xml file), and since the numbers are
sequential they're easy to use when communicating with other people
(friends, Web site visitors, potential licensees) than timestamps.

For my audio files, I just use UUIDs, which are downright unfriendly
but easy to generate and discourage "poking around" in the URL space.

And people move around so much, too. So you might have an American who
was raised in another country and still uses that format, just as you
might have someone from England who was born and raised in the US.

People don't always use the date format you'd expect based on where they
have just come from.

Maybe that issue is more typical of Canada than other countries, because
we're often partway between the US and UK in usage, and individual
Canadians don't always agree on which parts are to be borrowed from the
US and which from the UK.

The Russians, IIRC, use Roman numerals for the month, so that 4 July
2010 comes out 4 VI 2010.  This meant that V & I had to be on Russian
typewriters, tho they do not occur in the Russian alphabet.

Actually, the character "I" did exist on Russian typewriter keyboards prior
to 1918, but a spelling reform did away with that letter and it is now
completely supplanted by "И".
The character "V", however, has never existed on any Russian keyboard.
Russians may use Roman numerals to indicate dates in handwriting, but not in
typing or word processing.

If you say so.  I can't remember where I learned what I wrote, and
have no idea how I could look it up.

Actually, the prerevolutionary alphabet also contained a letter
("izhitsa") that looked like V with a hook on the right.  I have seen
Roman numerals typed using that, so perhaps, on some Soviet
typewriters, it survived as well as the I.

The izhitsa " Ѵ "   _may_ have survived on _some_ Russian typewriters, but I
doubt it.  It was pretty much phased out in favor of the " и " by the time
typewriters were manufactured.  I have seen it used in books in place of the
"V" for Roman numeral purposes, but never on a typewriter keyboard.  Here is
a pic of three pre-Revolutionary Russian typewriter keyboards:

Very likely I saw it in a book & misremembered it.

What interested me about those keyboards was the position of ц and э,
both of which now appear, as one would expect, among the other letters.
I was particularly surprised that ц was stuck up among the numbers, as
it is a fairly common letter.

I suspect they may have been initially constrained by existing configuration
of the mechanical keyboards, which were US- or European-designed and which
didn't allow for the 35 pre-Revolutionary letters to be neatly consolidated
on 3 rows, so a couple letters had to end up on the top row.

P.S. I thought that  " ц " was fairly common as well, but it turns out that
it ranks near the bottom in terms of frequency ---- 30 out of 33 letters
currently used.  ( "э" was only slightly more frequent at 28 out of 33)

Getting rid of the Tsar could have been a serious blow to " ц ", but
seemingly endless writings that followed on the topic of "социализм" ensured
that its ranking slipped no lower . . .

Yes, I'll agree that checks are *obsolescent* but will not be obsolete

Some are, some aren't.  The ones at

   http://www.walmartchecks.com/line.aspx?lineid=53

all seem to have the "20" on them, as do some of the ones at

   http://secure.checksinthemail.com/

Back in the late '90s, it was reasonable to drop the pre-printed
century, as people could expect to still be using the same batch of
checks when the century rolled over, but few people now will expect to
still be writing checks in 2100 on batches they buy today (or at all,
for that matter).  So I suspect that including it will go back to
being the default.

It's a good deal older than that in principle. Befor 1988 it would have been
written with spaces instead of hyphens 2010 02 14. In 1988 hyphens were added.
It's been the official form in South Africa for numerical dates since 1972.

To be consistent with the writing, we can say, for example, "Twenty
Ten,  February the Fifteenth" for 2010-02-15 in speech. The leading
zero as in "02" makes the length for all dates the same and convenient
for file management.
