Examples

For Series:

>>> s = pd.Series(["1/1/2020 10:00:00+00:00", "2/1/2020 11:00:00+00:00"])
>>> s = pd.to_datetime(s)
>>> s
0   2020-01-01 10:00:00+00:00
1   2020-02-01 11:00:00+00:00
dtype: datetime64[s, UTC]
>>> s.dt.tz
datetime.timezone.utc

For DatetimeIndex:

>>> idx = pd.DatetimeIndex(
...     ["1/1/2020 10:00:00+00:00", "2/1/2020 11:00:00+00:00"]
... )
>>> idx.tz
datetime.timezone.utc
