Confusingly (or not, when you think about it), its the other way around:  
so, "16:32 CET" can be written "16:32 +0100".  This is the same time as
"15:32 +0000" or "15:32 UTC".

So, whenever you want to convert from localtime to UTC you *subtract* the
second number from the first.

See rfc2822 for more details.
