In DST the offset from UTC is adjusted and thus it will become +2 in your
case. Perhaps a note about DST would be usefull. The original idea was to use
the POSIX 1003.1 timezone string that optionally includes the DST information
but this introduces a lot of complexity and was changed to include just the
current offset.

Perhaps you didn't had a need about this in the past. Have you ever tried
looking at graphs that include time information in them? Just have a look at
mrtg graphs or stock graphs and try to figure what time each point is
supposed to represent.
