+        Python's standard `datetime` library uses a different representation
+        timedelta's. This method converts a Series of pandas Timedeltas
+        to `datetime.timedelta` format with the same length as the original
+        Series.
+
+        Returns
+        -------
+        a : numpy.ndarray
+            1D array containing data with `datetime.timedelta` type.
+
+        Examples
