I am using .update() because I want to override the original time. However, the time does not seem to have been changed following this step.

import pandas as pd
import xray
import pytz   

ds = xray.open_mfdataset('/DATA/WRF/_/_/*T_SFC.nc')               

time=ds['time'].to_index()

time_utc = time.tz_localize(pytz.UTC)
au_tz = pytz.timezone('Australia/Sydney')
time_local = time_utc.tz_convert(au_tz)

#convert pandas datetimeindex to a series and then series to xarray dataarray and then to xray dataset
local_series=time_local.to_series()
local_da=xray.DataArray.from_series(local_series)
local_ds=xray.DataArray.to_dataset(local_da)

#create a new dataset that replaces/updates the UTC time in the original dataset with the local time from the newly created dataset (in pandas)
new_ds=ds.update(local_ds)

If so, that would surprise me. We do not have any methods related to timezone support in xarray.

That said, it _should_ **probably** work (not tested) to manipulate `ds['time'].to_index()` as a pandas Index and then save it back in an xarray Dataset.
