'all broken'? Nah, not really. A semi-working feature sometimes is 
better than none at all.

Hm, yes, but why sometimes? During daylight savings time?

Not true afaik. I added support for minutes in timezone offsets merely
as an exercise, and it worked for me (but i don't need/use that feature).

Note that i consider my c++ understanding quite limited as well.
So feel free to send patches to fix/improve timezone support, that
can only be a good thing!
