Running 11.2 with KDE. I multiboot so I don’t want ANY of the partitions changing the clock for daylight savings time. I can do it myself and know when/if it’s done, thank you very much. This change, I made what turned out to be the MISTAKE of allowing opensuse 11.2 to be running during the change and the clock got changed. Well, “fool me once, shame on me”. I can’t find a configuration setting to control daylight savings time. What I want to do is set Linux/KDE so it DOES NOT change the clock. Can someone tell me where it is?
Maybe you can set the hardware clock to UTC. This way the hardware clock is
not changed for daylight saving time.
Linux supports this (can be configured in Yast) and looks like Windows
supports it:

Then ask in the BETA forum.
I’ll answer guessing it behaves like any stable openSUSE.

You can not find it because Linux DOES NOT change the clock.
Linux runs internally in what “looks” like UTC, Universal Time Coordinated.
Then it uses tables to convert the time to local time for displaying
whatever is the correct local time for each user. If the locale specifies
that there is a daylight time change to apply, it is applied for that user
for display only. The real clock does not change.
If the locale change is incorrect, like happening in the wrong day, or in a
country that does not have it, then it is a bug you have to report, with
proofs, on bugzilla.
Now, there is another clock in the system, the CMOS clock. This clock can
be set to run using local time or UTC time. Your mistake was telling it to
use local time, which is adjusted. Change it. Yast.
However, if one of your systems is Windows, use local time, and on daylight
change, live with it and change the clocks back. Or use UTC and adjust
windows instead. Several linux systems can live together if the cmos clock
uses UTC time, but with windows in the mixture it is not possible. If local
time is used there, hell breaks loose.

If you are multibooting with Windows, and your Windows versions are Vista or Windows 7, then try setting the cmos clock to UTC. For a guide on how to do that, see BIOS clock setup with dual boot
If you set the hardware clock to UTC, daylight saving is automatically enabled because the time that appears on screen is the locale time which supports daylight saving where appropriate.
If you do not want Linux to handle the daylight saving, leave the hardware clock to the locale setting. What happens will then depend on whatever OS you have installed. If, on a dual-boot Windows machine, Windows changes the hardware clock then the change will appear in Linux. You may have to check the appropriate combinations for the OS you are running.

11.2 past its end of life already (cite: http://en.opensuse.org/Lifetime
) and you should either upgrade to a supported version or alternatively
join project Evergreen http://tinyurl.com/4aflkpy and join the mail list
listed on that page for your support questions…
