To be honest I didn't know it was possible to open a Dataset and maintain np.datetime64[us] values. I feel like casting maybe should occur automatically -- we do this already in other contexts, e.g.: ``` In [3]: da = xr.DataArray([np.datetime64("2000-01-01", "us")], dims=["time"], name="time")

In [4]: da Out[4]: <xarray.DataArray 'time' (time: 1)> array(['2000-01-01T00:00:00.000000000'], dtype='datetime64[ns]') Dimensions without coordinates: time ``` I'll try and dig deeper into this in the next few days, but @keewis's workaround should be good in the meantime.
