Description

Currently, duration is not yet supported in basic cast operations (using the python binding from ARROW-5855, currently from my branch, not yet merged):

In [25]: arr = pa.array([1, 2])

In [26]: arr.cast(pa.duration('s'))  
...
ArrowNotImplementedError: No cast implemented from int64 to duration[s]

In [27]: arr = pa.array([1, 2], pa.duration('s'))  

In [28]: arr.cast(pa.duration('ms'))
...
ArrowNotImplementedError: No cast implemented from duration[s] to duration[ms]
