Update: I was mistaken about the nature of the issue. I can load someone else's data with a datetime64[ns] dimension and select from it just fine. Meanwhile, I cannot select from my DataArray, even when I have replaced the datetime64[ns] dimension time with float64 values.

```

spgs = xr.open_dataarray("mydata.nc") print(spgs)
