xarray/tests/test_backends.py::test_use_cftime_false_standard_calendar_in_range[standard]: pandas._libs.tslibs.np_datetime.OutOfBoundsTimedelta: Cannot cast 0 from D to 'ns' without overflow.

and the like seem to be caused by the following minimal example (pandas-dev/pandas#56996):

>>> pd.to_timedelta(np.int32(0), "D")
Traceback (most recent call last):
  File "conversion.pyx", line 228, in pandas._libs.tslibs.conversion.cast_from_unit
OverflowError: Python integer 86400000000000 out of bounds for int32

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "timedeltas.pyx", line 377, in pandas._libs.tslibs.timedeltas._maybe_cast_from_unit
  File "conversion.pyx", line 230, in pandas._libs.tslibs.conversion.cast_from_unit
pandas._libs.tslibs.np_datetime.OutOfBoundsDatetime: cannot convert input 0 with the unit 'D'

The above exception was the direct cause of the following exception:
