Yes, I know. But I wonder if that's what they mean by "modifies a noun".

I'm not convinced that it really is adverbial, rather than adjectival.

You'd be right not to be convinced -- it IS adjectival. That's when the
apostrophe is required.
Perhaps this is the best way to tie my rule in with the Guardian's:
when the period modifies a noun, it's adjectival and represents "<noun>
OF <period>" -- possessive in form and requiring the apostrophe; when,
on the other hand, the period modifies an adjective, it's adverbial and
represents "<adjective> FOR <period>" -- not possessive in form and not
requiring the apostrophe.
