Something I posted hours ago now claims to have been posted ten minutes ago, and indeed, when I look at the absolute timestamp (0:22 local time) vs. the clock (0:32 local time) that's true, so there's something amiss with your timezone calculations, I think.

Let's see what time this post ends up being stamped, versus what time it currently is.

Be right back...

Okay, the BBS says I posted that at 03:34, but it''s actually 00:34, so it's off by three hours.

Gotta be a timezone issue. Maybe adding an offset when it should be subtracted, I dunno. Or maybe the time on the server is just set wrong.

I get the same thing, timestamp offset by -5 hours (compared to UK GMT time)

Interesting that your gap differs from mine. Has to be a time zone thing then. If it were just an incorrect server time, it'd be the same for both of us.
