XF 1.5 Timestamps are 1 hour off


Active member
Last night, a bunch of my members started noticing that timestamps appeared to be off. I tested myself and am seeing the same thing. I've double-checked my timezone to make sure it's not off (set to EST time).

When I posted something recently and then checked it's timestamp, the relative timestamp said "2 minutes ago", but the full timestamp was for an hour ago.

Any suggestions?
