I think I have implemented items 1 and 3: perhaps you could take a look to see 
if you have what you need?

For item 3, look in particular at the KTimezoneSource class...all that should 
be needed is to follow the instructions given there. If you need, the is an 
example called DummySource in the .cpp file - and I'd be happy to help of 

For item 2, I think that the building blocks are all there, but I'm not 
exactly sure what the best API would be. For example, would you want 
something like:

	QDateTime convert(const QDateTime &original, const KTimezone *newZone);

added to KTimezone?

Thanks, Shaheed
