polars.Series.dt.base_utc_offset#

Series.dt.base_utc_offset() → Series[source]#

Base offset from UTC.

This is usually constant for all datetimes in a given time zone, but may vary in the rare case that a country switches time zone, like Samoa (Apia) did at the end of 2011.

Returns:

Series: Series of data type Duration.
