clock wrong after daylight saving time
Last modified: 2005-12-20 16:14:11 UTC
After I set my clock to daylight saving time, it terribly goes wrong and this stupid /etc/adjtime is again there. I am scared for beginners with Linux - it took me years to find out /etc/adjtime is the file disturbing my clock.
Hello This problem is `known'. But please provide some more information. Attach the file /etc/sysconfig/clock as well as the content of /etc/adjtime.
Please also check if the timezone set in the BIOS of your system is the same as specified in /etc/sysconfig/clock - the problem is likely caused by this.
I do what you say - however I am trying here to help you (even more) improve your distro - I can quite easily get this right by deleting /etc/adjtime.
There is no BIOS timezone setting in my system.

Werner: The clock is set to localtime. Please comment about this.
From where do you know this? I'd like to know which time in the CMOS is set before linux or any other OS is booted. Then ... _after that_ ... I'd like to know the settings in /etc/sysconfig/clock to see which is the assumption on the CMOS clock and the timezone of the system time. Also the lines found in /etc/adjtime I'd like to see. Then we will see if the configuration, the file adjtime and the CMOS time are consistent.
Btw: Which time was set to daylight saving time? The system time is set automatically to daylight saving time and back depending on the rules for the choosen timezone. And at reboot/shutdown this will be done automatically to the CMOS clock. The only problem which may occur are missed timer interrupts of the system time. This makes the system clock much more worse on some mainboards or notebooks than the CMOS time.
