Note that they mean subtly different things: CET is "Central European
Time", which has a fixed offset of one hour. Europe/Berlin rather means
"whatever offset is valid at this time" (which, as we have seen, is
ambiguous some of the time and faulty at the other end).

You want the second if you want to schedule a regular meeting in your
city at the local bar. You want the first in a log file.
