# xarray.CFTimeIndex.argsort

#### CFTimeIndex.argsort(\*args, \*\*kwargs)[[source]](https://github.com/pydata/xarray/blob/main/xarray/../.pixi/envs/doc/lib/python3.15/site-packages/pandas/core/indexes/base.py#L6325-L6366)

Return the integer indices that would sort the index.

This method returns an array of indices that indicate the order in
which elements of the index should be arranged to produce a sorted
index. It delegates to the underlying array’s `argsort` method.

* **Parameters:**
  * **\*args** – Passed to numpy.ndarray.argsort.
  * **\*\*kwargs** – Passed to numpy.ndarray.argsort.
* **Returns:**
  `np.ndarray[np.intp]` – Integer indices that would sort the index if used as
  an indexer.
