    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]
