Description

Even with the ARROW-1484 patch, we have:

In [10]: pa.array([0], type=pa.timestamp('ns'))
Out[10]: 
<pyarrow.lib.TimestampArray object at 0x7f9145b27098>
[
  Timestamp('1968-01-12 11:18:14.409378304')
]

In [11]: pa.array([0], type='int64').cast(pa.timestamp('ns'))
Out[11]: 
<pyarrow.lib.TimestampArray object at 0x7f9145b27d18>
[
  Timestamp('1970-01-01 00:00:00')
]
