Its that time of the year again when time changes and we have to make sure our servers are using the right zone with right time. Out of many servers I admin, I found 3 servers which had wrong time displaying. All of them had one thing in common, Fedora Core 4. So I fixed it by doing the folowing.

mv /etc/localtime /etc/localtime.old

ln -s /usr/share/zoneinfo/PST8PDT /etc/localtime
