If the proleptic gregorian calendar is enough, then
tmdate should work for you. It does not handle the
(locale-specific!) calendar changeovers. Our timezone
information simply doesn't encode calendar changes.
I'm not even sure if the IANA timezone database encodes
calendar changes.
I'd suggest using the proleptic gregorian calendar, and
converting from it as late as possible. Ideally never.
