Control: retitle -1 pandas: test-failing warning with new xarray
This is a warning being treated as an error, but the one in test_to_xarray (probably due to the new version of xarray), not the zoneinfo one. This is a FutureWarning, so it should be OK to *use* the current pandas with the new xarray.
The same warning happens in autopkgtest but isn't treated as an error there, so didn't block the new xarray.
I intend to try fixing this later.
