You can use the "zdump" to verify the DST rules. Substitute the right timezone in the command below:

You can see DST takes effect on March 11 this year, so the rules are updated. This output was from a CentOS 4 system, but I'd imagine the results should be the same on CentOS 3.
On a side note, but kind of on-topic, I want to set my box to live in a different timezone. In my case, I actually want the box to live in GMT +0000, how would I go about doing that? I have this sneaky suspicion it's a sneaky little file somewhere, but I haven't been able to locate it.
