Answer 1

Use the Series dt accessor to get access to the methods and attributes of a datetime (timedelta) series.

>>> s
0   -1 days +23:45:14.304000
1   -1 days +23:46:57.132000
2   -1 days +23:49:25.913000
3   -1 days +23:59:48.913000
4            00:00:00.820000
dtype: timedelta64[ns]
>>>
>>> s.dt.total_seconds()
0   -885.696
1   -782.868
2   -634.087
3    -11.087
4      0.820
dtype: float64
