Here's another way to see it. Let's get the Unix timestamp for right now: >>> from datetime import datetime >>> epoch = datetime(1970, 1, 1) >>> now = (datetime.now() - epoch).total_seconds() >>> now 1581261916.910558 Now let's figure out the resolution, by taking the next float up from that value and subtracting. >>> from math import nextafter, inf >>> nextafter(now, inf) - now 2.384185791015625e-07 That's 2**-22, or a little bit less than a quarter of a microsecond. We're out from our desired resolution (1ns) by a factor of ~239, so it's going to take another 8 bits (factor of 256) to get us there. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39484> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
