[CentOS] CentOS 6: hostname and timezone

Actually I already seem to have the correct timezone file,
but why is the time wrong?

afarber at CentOS-60-64-minimal:~> sudo diff
/usr/share/zoneinfo/Europe/Berlin /etc/localtime

afarber at CentOS-60-64-minimal:~> date
Wed Oct  5 00:35:39 CEST 2011

Should I:

   chkconfig ntp on
   service ntp start

Or is the reasone elsewhere?

Sorry for the basic questions, I'm new to CentOS 6
