I think it's useful to have this raise a custom exception
UnknownTimeZoneError, subclassed from ValueError. That satisfies those
(including me!) who think it should be a ValueError, while also making
the exception more specific so it can be handled apart from other
possible ValueError causes.

In short: +1 to ‘class UnknownTimeZoneError(ValueError)’.
