> The conversion itself works fine (eg when specifying {{type=pa.timestamp("us", tz="America/New_York")}} in the below example), but inferring the type and timezone from the first value fails if it has a zoneinfo timezone:
> {code}
> In [53]: tz = zoneinfo.ZoneInfo(key='America/New_York')
> In [54]: dt = datetime.datetime(2013, 11, 3, 10, 3, 14, tzinfo = tz)
> In [55]: pa.array([dt])
> ....
> ArrowInvalid: Object returned by tzinfo.utcoffset(None) is not an instance of datetime.timedelta
> {code}
