The clock goes back to GMT (I bet you're in US/Eastern). You screwed up the installation somehow. You've got 2 choices: 1. Keep bios with local time. Run yast as root: Administration->Time Zone. Select a zone, and then tell yast that your bios is local time - NOT GMT time. 2 (Preferred). Set bios to GMT. Do the same thing with yast, but tell it that your clock is @ GMT. This way daylight savings will be automatically activated. -- ET.

I don't know where this myth comes from. My desktop's hardware clock is set on local time and it makes the change to and from daylight savings time just fine. Probably someone screwed up the system clock implementation twenty years ago and the "fix" is still floating around. Jeffrey

This so-called myth comes from the fact that if Linux is not running when the change to/from DST occurs, Linux wont change the time. (How should Linux know that you did not have some other OS running at the time, which made the switch?) If you have the hardware clock set to GMT, it is the locale that translates from GMT to your time-zone that handles how to translate the time depending on the time of year. This will work just fine independently of whether Linux was running when the clock changed. Regards Ole -- Pro is to con as progress is to Congress.

Linux thinks your hardware clock is set to GMT. In /etc/rc.config, change this: GMT="-u" to this: GMT="" My advice, however, would be to keep your system clock using GMT, assuming Linux is currently set at the correct (local) time, and your time zone is set correctly, then use the following command (as root) to set your hardware clock to GMT: hwclock --utc --systohc Hope that helps, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\
