We raise a TypeError in the following example, because the dataset has datetime-type dimension. ```python In [3]: ds = xr.tutorial.load_dataset('air_temperature') In [4]: ds Out[4]: <xarray.Dataset> Dimensions: (lat: 25, lon: 53, time: 2920) Coordinates: * lat (lat) float32 75.0 72.5 70.0 67.5 65.0 62.5 60.0 57.5 55.0 52.5 ... * lon (lon) float32 200.0 202.5 205.0 207.5 210.0 212.5 215.0 217.5 ... * time (time) datetime64[ns] 2013-01-01 2013-01-01T06:00:00 ...

I agree for the object type dimension, such as string, reindex is be appropriate and users might expect it. But for datetime dimension, I think users expect the interpolation rather than reindexing. |
