all you have todo, if you don't want this change to be global, is
to change TZ before calling rrdtol, and then change it back to the
original value and call tzset() again ...

in php the calling of tzset seems to happen automagically when you
call putenv with a TZ variable.

the same would have to be be added to rrd_graph for this ... or are
you looking for something else ?

cheers
