Daytime Saving time. Cannot change time

arubin · 11-04-2004, 03:23 PM

Last weekend our clocks moved back an hour.

I was on my PC in linux at the time and I think the clock switched automatically.

Now, however it is showing an hour early.

I suspect that what has happened is that Windows has messed up the clock when it moved to GMT(I am running dual boot with Win 98SE)

Is there anything I can do about this.

Whenever I go into Control Centre Administrator mode to try and change the time the KDE control module crashes

Thanks.

daylight savings time came, your PC did the 'fall-back' thing, and now your clock is an hour behind?

--is this a dual boot?

As I wrote. This is a dual boot and I was wondering if Windows 98 has put back the system clock so Linux (KDE) is now showing an hour early.

You can use date from root right now it would be;
date 110418032004 which is 11/04 [today]1803 [my local time]2004[year]

oops... sorry i just skimmed it-- you're problem is that both OSes are rolling back for daylight savings time.

you should fix this so that only one OS will adjust time for DST

I have a similar problem on a dual boot. It seems that everything is fine as long as I run only one system. But if I switch between the systems (I just booted accidentally into Linux because Windows update wanted to reboot and Linux is my default system) the clock runs about 40 min late. In Windows, the automatic adjustment is switched off. On Linux however, xntpd is running. Could that be the problem?

'it seem everything is fine as long as you run one OS'
--yup, that's the point. as soon as DST rolls around and it's time to update your clock, your OS will recognize that and change your clock. so if you're running happily along in linux, DST comes and goes, and you then need to boot to windows for some reason, when you do, you'll get your clock mucked.

'about 40 mins late'.. eh, you got me on that one... i'm sure xntp is playing a role, though

I guess I found the solution (at least for my system): SuSE recommends to set the system clock to 'local time' instead of 'GMT' on dual boot systems, claiming that Windows uses the same setting. I now tried to use GMT instead and see, the clock runs correctly.

About those 40 min I am not that sure anymore

Maybe the clock wasn't set correctly... sorry!

yes, windows defaults to sys clock of localtime... when running dual boot, you need to think about both/all OSes when considering the clock, and i like to recommend that the OS you use most on any multi-boot box be the ONLY one set to roll the clock for DST

Thanks. I have reset the date in linux is advised by comprookie2000 and turned off automatic DST changing in Windows. The times are right now in both.
