I sorted out my M1 python installation and can reproduce: In [21]: ds_r.time Out[21]: <xarray.DataArray 'time' (nt: 10)> array(['2022-01-01T00:00:00.000000000', '2022-01-02T00:00:00.000000000', '2022-01-03T00:00:00.000000000', '2022-01-04T00:00:00.000000000', '2022-01-01T00:00:00.000000000', '2022-01-06T00:00:00.000000000', # Note the first value on this line! '2022-01-07T00:00:00.000000000', '2022-01-08T00:00:00.000000000', '2022-01-09T00:00:00.000000000', '2022-01-10T00:00:00.000000000'], dtype='datetime64[ns]') Dimensions without coordinates: nt

It's quite surprising we get '2022-01-01T00:00:00.000000000' rather than NaT — why the beginning of the year?!

I suspect it's not directly an xarray issue given Xarray is only python code, and python code does not directly branch by CPU. I've frequently had issues like this where it's difficult to understand which library is responsible, I'd welcome any more investigation here.
