I have a Centos 5.5 server with no GUI installed. I have several times changed the timezone by copying the correct file to /etc/localtime, however something keeps changing it back. I'm not sure if this is a yum update or what. Without installing the graphical tools, how can I update the timezone in such a way that the /etc/localtime file won't keep getting clobbered.
/usr/bin/system-config-time
(from the system-config-date RPM package)
It will work in text mode.
(Essentially /etc/sysconfig/clock is the config file that also needs updating)
