How to Covert from prolepticGregorian to datetime

Question

I'm having issues to convert a dataframe with a prolepticGregorian (Comming for netCDF4) to a datetime, using

i3h.index = pd.to_datetime(i3h.index, format='%Y-%m-%d %')

And the error is

<class 'cftime._cftime.DatetimeProlepticGregorian'> is not convertible to datetime

How is possible to do it? I need it to use the .resample("1H").mean()

The Dataframe looks like the following

i3h

rsds_nc = Dataset(rsds_nc_filepath)
rsds_data = rsds_nc.variables['rsdsAdjust']
rsds_data.set_auto_mask(False)
times = rsds_nc.variables['time']
time_convert = netCDF4.num2date(times[:], times.units, times.calendar)

DatFrame1 = pd.DataFrame(columns = range(len(lats)),index = time_convert[yr_id_start:yr_id_end])
