Assigning a timestamp value to a Series create an int instead

[jimbasquiat]

g = pd.Series(dict(a = 5, b =datetime(2018, 1,1)))
g['datetime'] = pd.Timestamp('2018-01-02')

g returns:

a                             5
b           2018-01-01 00:00:00
datetime    1514851200000000000
dtype: object

It seems this is a bug, I asked the question on SO and found a workaround, but might be useful to investigate further and fix the bug.
