Sharing XP and Gentoo on my system messes up system time.

Hi all,

Just wondering if anyone else has had the same problem as me. I have a dual boot laptop (XP and 2.6.9-gentoo-r9). Whenever I boot into Gentoo after having been in my XP partition, my system clock is off by 2 or 6 hours.

I noticed that the time is off in XP when I first boot it up, but XP "corrects" itself.

I am in Minneapolis MN, USA. That is in the Central Standard Time Zone. I had made a link in /etc/localtime before I built the kernel like so:

Code: Select all

ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime

However, that link isn't valid anymore. Maybe because I used KDE to adjust the time???

So, does anyone have any ideas how to stop this from happening? It isn't the end of the world, just annoying. Plus, if we could, it would be nice to fix it a la XP whereby it sees that the time is off when it boots up and corrects it.

Thanks,

are you usually connected to the internet when you boot up ? because you could try using ntp
Which checks a servers time and automatically corrects your clock at boot time
you should also remake that link.
also is XP set to the correct time zone ?

If you don't want dual-boot to mess with your time you should change

Code: Select all

CLOCK="UTC"

to

Code: Select all

CLOCK="local"

in /etc/conf.d/clock. Windows stores the local time in the hardware clock while Linux stores the Time in UTC (a.k.a. GMT) per default so the hardware clock is not affected by daylight saving time changes. With the above mentioned change you can switch Linux to interpret the hardware time as local time instead.

I always run ntpclient at startup to sync the clock on my machine with a known timesource.

emerge ntp
should get you going...

Hey all,

Thanks so much for the fast responses. Unfortunately, I am not always connected to a network at bootup, so I don't think that ntp is "the" solution.

I am interested in the post by Taladar however, I don't have a file named /etc/conf.d/clock. Is that file part of a specific package?

Thanks,

IT's actually in /etc/rc.conf
Try it.

Thanks Dgege,

I've made the change and will give it a test here shortly.

rc.conf will do the trick.

dont forget to remove /etc/adjtime after you change that value, and reboot.

should be working fine... (to think it took me the thick end of a year to figure this out....:S)

It's not anymore. If you updated your system recently, the next time you boot up you'll find a message telling you not to use /etc/rc.conf but /etc/conf.d/clock

It's been awhile since I used windows but I was almost sure you could set it to use UTC as well. So I did some searching and found this gem that explains the problem. http://weblogs.asp.net/oldnewthing/arch ... 24672.aspx . Every time someone asks me why I don't use windows any longer I think of things like this.
