    In the meantime I am using the following Python 2.7 script to add timestamps in the style of the Python logging module. Make sure to use Python's -u Option to disable output buffering.
$ python -u timestamper.py sh -c 'echo hey; sleep 1; echo ho'
2017-05-08 09:17:56.517 hey
2017-05-08 09:17:57.520 ho
