[opensuse] opensuse 11.0 x64 time messed up with dual boot
I sent an email about this a couple of weeks ago but got no feedback from anyone. I also googled unsuccessfully... Basically my opensuse 11.0 is set to sync date/time with UTC and that works fine. However, this is a dual boot machine (sorry VM windows is not fast enough for the graphic applications I need to occasionally use) and after booting windoz and back to opensuse, the clock is messed up! I do not understand why UTC sync-ing at boot is not resetting the time/date to the correct values. Is this broken, or do I need to get a newer version?

If I remember correctly windows requires the bios time be set at the local time. OpenSUSE will store the time in UTC which is several hours different from your local time depending where you are.

Linux can be configured to set the hardware clock to either local or UTC time, though all Linux/Unix time stamps are UTC and then converted to local time. I don't know if it still occurs, but years ago, when logging into a Windows domain in a different time zone would change your computer's time. Such a thing wouldn't happen in Linux, where everything works in UTC. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I believe you will need to adjust to use Local Time instead of UTC, since that is all you can do with Windows, and if you dual boot they need to agree what time IS the BIOS clock. -- Joe Morris Registered Linux user 231871 running openSUSE 10.3 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

This is exactly what I had to do with a new laptop I bought this week. HPdv9925nz with everything working out of the box except wireless. Set your time to local and the problem will disappear. -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi Vahe, If windows time is OK, than your windows are set to synchronize time with external source on the Internet. Windows consider that hardware clock is set on local time and there is no way to change that. When you boot to windows it will check Internet (NTP server), see that hardware clock is off and it will set hardware clock to correct time. Default for any *nix, including linux, is to consider that hardware clock is set to UTC. When you boot in linux it will read hardware clock and set correct operating system time according to time zone you are in. As there is no way that you can tell windows that hardware clock is set to UTC (they always know better what you want), you have to change setting in linux to Local Time and everything should be good. That option is there only to compensate for lack of such setting in windows. -- Regards, Rajko http://en.opensuse.org/Portal needs helpful hands. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Vahe, I don't know enough about the details to tell you where your problem may lie, but I can tell you dual boot should work without issues. I have about 5 systems that dual boot Win and Linux and the time works without a hitch. As others have told you, windows stores time in local time while Linux likes to store time in UTC (Universal Coordinated Time)** but will store time in local time to accommodate a dual boot system. Generally, you want to get the windows clock set right first (use the ability for windows to update to internet time) and then boot to Linux. Use Yast -> System -> Date and Time to configure your timezone and _uncheck_ the box that says "Hardware Clock set to UTC" and your times should then match. To take advantage of the ntp date capabilities in Linux you will need to set the IP address of a time server for you to sync with in /etc/ntp.conf. Just google "ntp servers" and find a public server near you to sync with. Make sure the time is "reasonably close" but not "ahead" by more than a minute or two before syncing or that can cause problems. (computers freak out when time moves backwards. Once it is set, you shouldn't have an further problems. **[they must have been drunk when they arrived at the acronym]. -- David C. Rankin, J.D., P.E.
