What timezone should you use for your server? Perhaps you should try Universal Co-ordinated Time (UTC).
vi /etc/sysconfig/clock and change the UTC line to: "UTC=true"
Set localtimezone to UTC: ln -sf /usr/share/zoneinfo/UTC /etc/localtime
If you want to set your timezone to something else, perhaps your personal timezone, then you find that timezone under /usr/share/zoneinfo and link that to /etc/localtime. For example: ln -sf /usr/share/zoneinfo/Australia/Brisbane /etc/localtime.
