In
order to change the timezone of your system you will need to access the file /etc/sysconfig/clock directly:
#ZONE="America/New_York"
ZONE="GMT"
UTC=false
ARC=false
Note: If your
system's BIOS has UTC set to true, then set UTC to true. If it has it set to
false, set it to false. UTC in the configuration file must always reflect your
BIOS settings.
In order to get the
particular zone you wish to use you must associate ZONE with a file located
in /usr/share/zoneinfo. It is wise to note the directory structure because
if you need to set the timezone to that of Shanghai which is located in the Asia
directory you will then have to set your ZONE variable to the following :
ZONE="Asia/Shanghai"
Or perhaps you need
to set the timezone to that of East Brazil :
ZONE="Brazil/East"
Finally save the
file /etc/sysconfig/clock and on next reboot the system will be set
to the defined timezone.
For the time on the
machine to reflect the change timezone we need to link the zoneinfo file
to /etc/localtime. This can be done as follows :
If you are setting
your timezone to "Brazil/East" link the following file
to /etc/localtime :
# ln -sf
/usr/share/zoneinfo/Brazil/East /etc/localtime
Now by typing the
date command to display the time you should see if reflect the newly linked
timezone :
# date
Thu Sep 30 10:06:23 BRT 2004
Thu Sep 30 10:06:23 BRT 2004
