- - Any Linux gurus? (http://www.ironworksforum.com/forum/showthread.php?t=95088)

I decided to take the plunge and am no running Ubuntu. I dual boot into XP Pro for games occasionally, but everything else is Ubuntu.

Ubuntu recognizes system time correctly, but when I boot from Ubuntu to XP, XP thinks I'm 6 hours ahead. If I change and then reboot back to XP, it's fine and when I cold boot to XP it's okay as well.

WTF? Help...

Well that is the wierdest Linux problem I've ever heard...

Since XP pulls it's time from System BIOS, I'm a little concerned.

I've had similar issues with XP keeping time, then I found that the simplest answer was the right one.

right click the time on your desktop. click adjust time/date, click timezones tab. Make sure the appropriate one is selected for your area. If the time zone is right and your time is still wrong, sorry can't help there.

It's a known issue.

Basically, Linux by default sets the clock to GMT by default and then adjusts the time as per your preferences. Windows on the other hand just takes the BIOS clock as your local time full stop.

Combining the two approaches leads to what you're experiencing.

(and IIRC you get a strong recommendation in the Ubuntu installer to pick what I'm about to tell you ;) )

Anyhoo, it's far easier to fix it at the Linux end of things:

Simply have a look inside /etc/default/rcS and check that you have this:

Quote:

UTC=no

I suspect you're set to 'yes' at the moment so you'll need to change it. (eg at a console type sudo gedit /etc/default/rcS)

Hope that helps [img]smile.gif[/img]

Edit: Found this decent explanation:

Unfortunately, the standards about the UTC setting are different in the Windows and the Unix world. Windows interprets the system clock as local time, Unix by default as UTC. Since the bios is a shared space between all operating systems installed on a computer, it is not possible to talk about a default setting.

At the end of the day this is a matter of the way a machine is being used - the Windows choice is the more natural for personal workstations and departmental servers, the Unix choice makes sense for larger server installations with clients in multiple time zones. In addition, the Windows option is the more intuitive.

A typical PC user (I guess that this also the Ubuntu target group) expects that his or her computer is treating time the same way than watches and cell phones (that is as local time).

Ubuntu is Gnome, therefore, do it the common sense way. Place your mouse pointer onto your date/clock, right click the critter, select adjust time, type in password at console, then click select timezone and adjust it to your zone. Issue resolved.

Time Zone is set as it should be.

The problem isn't with Ubuntu, it's with WIndows.

Zebo, this does not sound right. Check your BIOS setting then. M$ reads the BIOS to set OS clock. Linux uses GMT time server to set the BIOS clock, then preferences the OS time for setting. I have never experienced this issue before. I run Ubuntu 5.10, with about 65% of the current updates. Their is a kernel that reconfigures my 3-D card, so I have not updated since = well there are 70MB worth of updates I have not touched. Hmm, maybe there lies the issue.

Unfortunately there's also an actual bug with how the Ubuntu clock applet handles UTC. Checking or unchecking the UTC box doesn't do diddly-squat for some people which is why I suggested changing it at the console.

So did it work Zebedog? [/QUOTE]Like a charm! [img]graemlins/thumbsup.gif[/img] Thank's to all for their input.

So far, I'm impressed with Ubuntu.
