Timezone support in the nagios core is something I'd rather not see, as
I really can't see any point at all in it. For the gui, that's a different
kind of ball entirely. Could you name a couple of usecases where it would
be useful if the scheduler is timezone aware?
Supporting timezones in a busy scheduler such as nagios is very, very far
from trivial (actually, timezones are piss-easy; It's DST's and how to work
around them that's hard, but timezone support without that is just a joke
anyway, so why bother?).

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
