Presumably everyone already knows that the timezones are more complicated
than hoi polloi believe? The offsets are not always integer values of
hours. For example, Newfoundland time is UTC−03:30. Additional
complications include daylight saving time and the many historical
versions of timezones. The definition of UTC can remain pretty much
constant, but local-timezone time varies as a function of both location
and calendar date.
Allowing user-defined functions (as simple or as complicated as one
desires) for translation from UTC might be best.
