None of which answer my question. How, in Python, do you get an aware UTC datetime object? I know how to get a numeric representation of the time as the number of seconds since the Unix epoch. That's not what I asked. > So maybe the key is to use utcfromtimestamp()? I don't know. So, I'm really confused what point you're trying to make. You started out arguing that I should be using aware datetimes instead of naive datetimes. I said that the reason I don't use aware datetimes is because they're so much more difficult to generate. You said they were simple to generate. So, I'd like to see your code which generates an aware UTC datetime object in Python. And then we can argue about whether it's simple or not :-)
