Hi,
it seems, datetime has support for microseconds
datetime.datetime(year, month, day, hour=0, minute=0, second=0,
microsecond=0, tzinfo=None)
http://docs.python.org/3.3/library/datetime.html#datetime.datetime

I haven't done anything using this precision, but I guess,
microseconds could be used out of the box; for some higher precision,
you'd probably need to code your own datatype.

hth,
