Re: Column value not getting updated

[Jonathan Haddad <jo...@jonhaddad.com>]

It's not enough to set up ntp, you're going to need to force the time to
sync.  ntp is only meant to correct for drift.

You can either use ntpdate or I think there's a flag for ntpd (that I can't
remember and am in a rush out the door) that you can use to force it to
adjust to the correct time.
