There are two ways to handle this:
- If you don't want xarray to convert from datetime64 to numbers when saving the netCDF file, you need to convert the data yourself to a float or integer array.
- If you do want to make use of xarray's automated conversion, you need to specify units in `encoding` instead of `attrs`.

If something else seems to be going on, please share the result of calling `.info()` on your dataset.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,216626776

It looks like this error message is not very helpful currently -- a PR to improve it would be appreciated!","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,216626776
