It might be useful if timedelta were to get an isoformat() method. ISO 8601 specifies formats for durations; most people are familiar only with the date amd time formats. There are variations available but PnDTnHnMnS is probably the best. The biggest timedelta unit is days. Years and months are not appropriate. -- Pete Forman -- https://mail.python.org/mailman/listinfo/python-list
