185709414 MDU6SXNzdWUxODU3MDk0MTQ= 1064 Differences on datetime values appears after writing reindexed variable on netCDF file 16919188 closed 0     12 2016-10-27T15:54:34Z 2023-09-24T15:05:27Z 2023-09-24T15:05:27Z NONE      

In my Dataset i've got a time serie coordinate who begins like this

<xarray.DataArray 'time' (time: 10)> array(['2014-02-15T00:00:00.000000000+0100', '2014-02-15T18:10:00.000000000+0100', '2014-02-16T18:10:00.000000000+0100', '2014-02-17T18:10:00.000000000+0100', '2014-02-18T18:10:00.000000000+0100', '2014-02-19T18:10:00.000000000+0100', '2014-02-20T18:10:00.000000000+0100', '2014-02-21T18:10:00.000000000+0100', '2014-02-22T00:00:00.000000000+0100', '2014-02-23T00:00:00.000000000+0100'], dtype='datetime64[ns]') Coordinates: * time (time) datetime64[ns] 2014-02-14T23:00:00 2014-02-15T17:10:00 ...

And all is ok when I write and re-open the netdcdf file

Then i try to add to this dataset a reindexed variable like this

da["MeanRainfallHeigh"] = rain.reindex(time =da.time).fillna(0)

Everything is still good for the writing, but when I reopen the netcdf file, the time values are modified for the minutes part.

<xarray.DataArray 'time' (time: 10)> array(['2014-02-15T00:00:00.000000000+0100', '2014-02-15T18:00:00.000000000+0100', '2014-02-16T18:00:00.000000000+0100', '2014-02-17T18:00:00.000000000+0100', '2014-02-18T18:00:00.000000000+0100', '2014-02-19T18:00:00.000000000+0100', '2014-02-20T18:00:00.000000000+0100', '2014-02-21T18:00:00.000000000+0100', '2014-02-22T00:00:00.000000000+0100', '2014-02-23T00:00:00.000000000+0100'], dtype='datetime64[ns]') Coordinates: * time (time) datetime64[ns] 2014-02-14T23:00:00 2014-02-15T17:00:00 ...

Thanks!
