@jbrockmendel likely knows more about the index arithmetic issue.

```python In [22]: import xarray as xr

In [23]: import pandas as pd

In [24]: idx = pd.timedelta_range("1D", periods=5, freq="D")

In [25]: a = xr.cftime_range("2000", periods=5)

In [26]: idx + a /Users/taugspurger/sandbox/pandas/pandas/core/arrays/datetimelike.py:1204: PerformanceWarning: Adding/subtracting array of DateOffsets to TimedeltaArray not vectorized PerformanceWarning, Out[26]: Index([2000-01-02 00:00:00, 2000-01-04 00:00:00, 2000-01-06 00:00:00, 2000-01-08 00:00:00, 2000-01-10 00:00:00], dtype='object')

In [27]: a + idx Out[27]: CFTimeIndex([2000-01-02 00:00:00, 2000-01-04 00:00:00, 2000-01-06 00:00:00, 2000-01-08 00:00:00, 2000-01-10 00:00:00], dtype='object') ```
