For SUSE Linux versions up to 7.3 change the file /etc/rc.config.
For SUSE Linux 8.0 and later, change /etc/sysconfig/clock as follows:
local: GMT="" GMT: GMT="-u"
Make sure you choose the right timezone.
To set the time, use the date command, such as "Thu Jul 10 19:09:00 MEST 1997":
(Format: MMTTSSMMJJJJ ) or with the ISO-format:
date -s '1997-07-10 19:09:00' +'%Y-%M-%d %T'
Settings of the CMOS-clock
The clock command writes and reads the CMOS clock. If you choose GMT for the CMOS clock, you have to set the clock command always with -u. e.g.:
+/kfr $ clock -ur
Thu Jul 10 19:15:10 1997
+/kfr $ clock -r
Thu Jul 10 17:15:11 1997
reads the appropriate timezone value and changes it to local time. Therefore the value is wrong. With
the CMOS clock receives its settings from the system clock.
Note: always choose Unix Single User Mode in the settings, in order to avoid problems with programs like make, rcs.
