What is your issue?

Hi all, Given the minimal working example bellow:

``` python import pandas as pd import xarray as xr

nc = xr.DataArray([[0]], dims=["x", "y"], coords=dict( lon=(["x"], [1]), lat=(["y"], [1])))

times_ = pd.date_range('2020-01-01', '2022-01-01', freq='1d') dt = times_[0] nc = nc.expand_dims(time=times_)

nc.sel(time=dt) nc.loc['time' == dt]

```

The nc.sel() part works like a charm, but the nc.loc[] return KeyError: "not all values found in index 'time'. Try setting the 'method' keyword argument (example: method='nearest').". Any idea what is happening there ? Considering I want to be able to edit the values of nc for certain sets of [x,y,time], my understanding is that I have to use loc[]. But it does not find the value dt whereas sel() does. How can I solve that ?
