Site Time

I've noticed something recently; that being a discrepancy between the site time and my computer's. Or something... I've noticed that recent posts only show as low as "1h" next to them. Even my own, when I've just posted them. When I click/mouseover the 1h it says they were posted an hour before they were actually posted (According to my time) (Which is PDT, BTW). Not sure if this is something I can change in my preferences (I don't see a timezone option) or something in the site itself.

EDIT: but it's synchronized with my phone time The one thing on mobile that actually works well
