1. For the reasons presented, I think it's worth attempting to define a common API that is based on datetime, but is tailored towards high precision time operations (at least using a different internal representation, perhaps supporting TAI).

This is a great opportunity to implement two requests at once. Some people want high precision datetime objects while others would like to see a datetime implementation that works with dates BC.

from datetime import datetime, timedelta epoch = datetime.datetime(1970, 1, 1) epoc - timedelta(days=1969*365.242) datetime.datetime(1, 1, 1, 12, 2, 52, 799998) epoch - timedelta(days=1970*365.242) Traceback (most recent call last): File "", line 1, in OverflowError: date value out of range

2. I don't think the stdlib is the right place to define the initial version of this.
