### Describe the enhancement requested `numpy` supports multiplying/dividing `timedelta` values with floats and performs automatic rounding to the current unit, e.g. ```python >>> import numpy as np >>> x = np.array([0, 1, 2, 3, 4, 5], dtype="timedelta64[s]") >>> x * 0.5 array([0, 0, 1, 1, 2, 2], dtype='timedelta64[s]') >>> x * 1.5 array([0, 1, 3, 4, 6, 7], dtype='timedelta64[s]') ``` This is very useful for ML applications where one needs to transform timestamps first to durations and then to floats (and back after performing a forecast). It would be very nice if `pyarrow` supported this as well, so one can directly work with arrow dtypes. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
