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.

Thank You,
