ds.time.values = pd.to_datetime(ds.time.values) + pd.DateOffset(months=2) By doing this, ds.indexes["time"] is not updated.

@folmerkrikken How about ds.assign_coords(time=pd.to_datetime(ds.time.values) + pd.DateOffset(months=2))

@shoyer I've seen this type of code elsewhere: direct assignment to .values and .data of a coordinate variable which then leads to inconsistent objects and confusing behaviour. Is there something we can do to alert users?
