Like Andreas pointed out, this seems an implementation detail. CET is
still +1, while CEST is +2.

If you take a look at the official IANA tzdata:


For europe, it's something like "std: CET" and "dst: CEST".

The current doc is not correct either; we should write something like
"either +1 or +2 depending on DST" (there seems to be a 2dst as well
which gets +3 offset);

Usually the best way of handling timezones is to use the proper
location format (e.g. TZ='Europe/Rome') and then letting the system
pick the proper offset; we might say something like ' "Europe/Rome"
which is +1 in winter ' in the doc, but I'd say that's nitpicking.
