That would be
class UnknownTimeZoneError(ValueError, TimeZoneError). As of today, in Pytz, UnknownTimeZoneError in fact subclasses KeyError. Any opinions against that?
Since the erroneous value is used as a key for a database lookup, and the error is probably detected by trying the lookup, I think that is ok. even if the user does not use []s.
There is no TimeZoneError today, and it would only be used for this UnknownTimeZoneError, so I'm not sure it has much value.
