File attachment 'added' time is incorrect

[robert.nadler@…]

Found in r6814.

The added time shown in the ticket is correct:

MTM1.log (1.6 kB) - added by admin 2 days ago.

but when you show the file, the added time is incorrect:

File MTM1.log, 1.6 kB (added by admin, 84 seconds ago)

The tool-tip timestamp is the same (and correct) on both.

sample file to see if problem with timestamps can be replicated

Yeah, it's because we're sending a 304 response in this case (trunk/trac/attachment.py@6980#L622​).

Maybe we can use the same approach as for changesets here (i.e. the less than one hour ago trick, trunk/trac/versioncontrol/web_ui/changeset.py@6980#L295​), so that we can at the same time show a valid information to the user and minimize the number of page reloads.
