However, I could well be wrong in that. Regards, Nick Maclaren.

However, I could well be wrong in that. I think we can ignore Solar* zones, but probably would be good if that %30 was %15 instead. Jakub

If you want historic ones as well then life gets much weirder. There are some 20 minute offsets as recently as 1951, for example. paul

I am not absolutely sure, but I think that I have lived in a country with no official time. I am certain that nobody actually used an official time if it had one, because there were no railways, and telephone calls had to be booked days ahead of time and were seriously unreliable. Even from the few places that HAD telephones! Assuming time zones that are a multiple of 15 minutes covers as many cases as are worth attempting to cover. Regards, Nick Maclaren.
