When you're writing the data back to disk with to_netcdf, try writing something like: ds.to_netcdf('somefile.nc', encoding={'time': {'units': '01-JAN-0001 00:00:00'}}).

But I'm a little surprised this doesn't work by default. Xarray does use '2001-01-01' as a default reference time, but if you pulled the data from an existing dataset (rather than creating the time variable directly yourself such as with numpy or pandas), then it should save the original units in encoding attribute of the time variable, which should then be used to save the units that it writes to the file. If ds is the name of the dataset you open from OpenDAP or save to netcdf, what does the value of ds.time.encoding look like?
