So wtf is up with the post times?

[teh_d00d]

So I just made a post in general, and then immediately hit the link at the top to reload the main page and went back into general, and it said "9 minutes ago."  I hadn't posted it but two minutes ago at the most, but I chalked that up to random weird.  Then I went back to general 5 minutes later, and it said "7 minutes ago."  Then I went back after reading some more posts, say about three minutes, and it said "15 minutes ago."
My question is, why even bother to have times on the posts if they're always so grossly inaccurate?  Don't even get me started on the "three minutes until" stuff I see... I just want to as why have the feature?

*ask why have the feature.
Also, for the record, when I immediately hit to go back to feedback, this said "12 minutes ago."  Refresh, and it said 8.

Yeah, there's something fucked up with the post times.  I post something and something that was posted before me still remains on top, it's weird.

Yea I don't get the *10 minutes until* thing either.

You have entered a land where time stands still! You will never be the same again! ::finger::sinister::finger
