You should set the local time in BIOS.

Re: How to set correct time

+ 1 to openntpd. it keeps syncing with a time server. so you dont have to worry about it ever. Comes in extremely handy on older machines like mine where the clock starts lagging.

Re: How to set correct time

Another +1 for openntpd.
I use it on my home server and on all the other PCs that use Linux. The openntpd on my server syncs to a pool of servers located in my country. And it also presents itself as a NTP server on the LAN here, all the other boxes in the home (Windows and Linux alike) sync to it in turn.

Works flawlessly.

Re: How to set correct time

I also recommend OpenNTPD. It will use the internet to set the time on your computer. More information here: http://wiki.archlinux.org/index.php/Net … e_Protocol If you can read Chinese: http://wiki.archlinux.org/index.php/Net … 6%96%87%29

Re: How to set correct time

ntp or OpenNTPD FTW. (I'm using ntp)

Use which ever and never worry again about time.
It's not that hard to set and once you set it, you never need to worry again (, well only if you're reinstalling...)

or when booting windows on your other partition. somehow windows changes my time when I boot it. I read about this problem somewhere but forgot the elegant fix for this (I don't really care since I rarely boot windows) so I use ntp to set my time again.

Re: How to set correct time

if you have windows 7 (possibly with vista too) you can change some ridiculous hidden registry key to make it leave the time on UTC (usually it loads it as localtime, turns it into UTC, then offsets, then saves as localtime again...). I just let Windows run 5 hours ahead of the real time because I hardly use it .
