datetime seems to be broken WRT timezones (even when you add them)

Not here it doesn't:

>>> import datetime
>>> dt = datetime.datetime(2020, 1, 31, 1, 30, 45, 987654, datetime.timezone.utc)
>>> print(dt)
2020-01-31 01:30:45.987654+00:00
>>> print(dt.strftime("%s"))

That's the same erroneous result from my example.  The correct value
is again 1580434245.  Unless you've done something subtlely

Also it's only available on Python3, which may not be the end of the
world, but the tool I'm working on is--for the moment at
least--expected to work on both python2.7 and 3.  But it's irrelevant
if it doesn't give the correct result, which seems to still be the
