[issue40316] Add zero function to time, datetime, which acts as the use case of replace to limit resolution

New submission from Or Toledano : I propose the zero(time_unit) function, which replaces all time units with greater equal resolution than time_unit by 0. E.g. >>> datetime.datetime(2020, 4, 18, 12, 27, 30, 500).zero("second") datetime.datetime(2020, 4, 18, 12, 27) I

Or Toledano added the comment: The use-case for this method is to "limit" the resolution of a time object. I encountered the need for it when I needed to reduce the resolution of some timestamps, to compare them with timestamps of lesser resolution. I found the following SOF po
