I noticed that there is a difference between intervals when computed from timedeltas vs timestamps. Is this a bug? Thanks!

In [2]: import datetime as datet
In [3]: d0 = datet.datetime(2016,3,27)
In [4]: d1 = datet.datetime(2016,3,28)
In [5]: (d1-d0).total_seconds()/3600
Out[5]: 24.0
In [6]: (d1.timestamp()-d0.timestamp())/3600
Out[6]: 23.0

sorry it's resolved. it was a timezone issue:

In [2]: d0 = datet.datetime(2016,3,27,tzinfo=datet.timezone.utc)

In [3]: d1 = datet.datetime(2016,3,28,tzinfo=datet.timezone.utc)

In [4]: (d1-d0).total_seconds()/3600
Out[4]: 24.0

In [5]: (d1.timestamp()-d0.timestamp())/3600
Out[5]: 24.0
