    Provides database store for pytz timezone objects.

    Valid inputs:
        * use_pytz=True:
            * any instance of pytz.tzinfo.DstTzInfo or pytz.tzinfo.StaticTzInfo
            * the pytz.UTC singleton
            * any string that validates against pytz.common_timezones. pytz will
              be used to build a timezone object from the string.
        * use_pytz=False:
            * any instance of zoneinfo.ZoneInfo
            * any string that validates against zoneinfo.available_timezones().
        * None and the empty string both represent 'no timezone'

    Valid outputs:
        * None
        * use_pytz=True: instances of pytz.tzinfo.DstTzInfo,
          pytz.tzinfo.StaticTzInfo and the pytz.UTC singleton
        * use_pytz=False: instances of zoneinfo.ZoneInfo

    Blank values are stored in the DB as the empty string. Timezones are stored
    in their string representation.

    The `choices` kwarg can be specified as a list of either
    [<timezone object>, <str>] or [<str>, <str>]. Internally in memory, it is
    stored as [<timezone object>, <str>].
