[CentOS] Time Change: Centos-immune?

Perhaps a naive question, but anyway:

Let's assume I'm running CentOS4 or RHEL4 and I updated it to 
tzdata-2007c. Before that, it was using an old tzdata package that did 
not have the US DST '07 patches.

Do I have to restart any service? ntpd?
How is the system going to figure out there's a new tzdata package 
installed? I guess _something_ needs to poll those files regularly and, 
if there's a change like the DST '07 patch, decide to make the change 
earlier.

Thanks,
