Incorrect server time

[dj_melayu]

Hello guys, recently I have a problem with my server time. I just want to know, how to fix it? For example, in my vbulletin forum, it says All time are GMT, the time now is 6.08am but the actual time is 9.08pm. I know the problem is not coming from vbulletin because after I reinstall again apache, the time is correct again. But now. it won't nomore. Please help me.
:P Thanks in advanced

It is a Vbulletin problem and your member problem.
http://YOURSITE/admincp/options.php?do=options&dogroup=datetime
And set your region's time. (This will be the default time for everyone.) (Also check Daylight savings time, if any.)

Then http://YOURSITE/profile.php?do=editoptions
Scroll down to Date and Time Options and set your region settings. (Also check Daylight savings time, if any.) Done.
(This is also where your users may enter their own timezone information.)

You didn't get what I meant. It's not about user options or vbulletin fault. It's a bout apache.
When I reinstall Apache, it will fix the problem sometimes. But now it won't fix it anymore.
Thanks for the 2 cent anyway :)

I use this in a shell script to update my server time

ntpdate europe.pool.ntp.org

Not sure if it could help you. I don't remember if I had to install ntpdate too, this was long ago, and I'm a unix noob.

Thanks. I've fixed it already. It was about OS time. Thanks for the helps :)
