Display datetime64 arrays without showing local timezones

See original GitHub issue

NumPy has an unfortunate way of adding local timezone offsets when printing datetime64 arrays:

<xray.DataArray 'time' (time: 4000)>
array(['1999-12-31T16:00:00.000000000-0800',
       '2000-01-01T16:00:00.000000000-0800',
       '2000-01-02T16:00:00.000000000-0800', ...,
       '2010-12-10T16:00:00.000000000-0800',
       '2010-12-11T16:00:00.000000000-0800',
       '2010-12-12T16:00:00.000000000-0800'], dtype='datetime64[ns]')
Coordinates:
  * time       (time) datetime64[ns] 2000-01-01 2000-01-02 2000-01-03 ...

We should use custom formatting code to remove the local timezone (to encourage folks just to use naive timezones/UTC).

The good news is that I fixed this display bug upstream in NumPy 1.11, which came out last month. If you upgrade to NumPy 1.11, datetimes are always treated as timezone naive. So I think we can actually consider this issue fixed.

sounds good to me, @sjpfenninger, but I don’t know the internals …
