2863 with abbreviated comments showing wrong time zone

The comments on ao3.org/comments were showing the server's time zone, not the user's. This also fixes the 500 error on that page.
All good, unless you have the time and inclination to humour a pedant and fix the spacing, which appears (in github at least) a bit out of whack, both here and for the new ```if``` above.
