1575010200,I_kwDOAMm_X85d4L-Y,7514,find daily maximum and associated timestamp to the hour in xarray,94073032,open,0,,,0,2023-02-07T20:56:21Z,2023-02-07T20:56:21Z,,NONE,,,,"### What is your issue?

Hello, 

I am finding myself in a puzzling situation with using xarray.

I need to find the daily maximum value of an xarray object but I also need to retain the associated time step to the hour, without losing that information, as instead happens with the resample functionality. There is usually a functionality, such as on=""time"", which would allow to read the field, but it does not seem to be supported by xarray.

Do you know if there is any other elegant way to do what I need to do?
I put a code snippet below

import xarray as xr
obj = xr.open_dataset(""/atmos.2019010100-2019123123.u_ref.nc"") # can be any nc file
obj = obj.resample(time='1D').max()

Many thanks for your help in advance","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7514/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,issue
