Your assumption is just a guess. Take a look at the python docs I linked just above here: "A naive object does not contain enough information to unambiguously locate itself relative to other date/time objects. Whether a naive object represents Coordinated Universal Time (UTC), local time, or time in some other timezone is purely up to the program"

I'd consider any datetimes that have an implicit timezone that isn't or might not be UTC a bug in any system.

This isn't restricted to python. Servers that spit out logs with timestamps, for instance, should be spitting out UTC.

It makes sense to build systems that deal with timezones at the very edges (and sometimes not even then) and use UTC for everything else. It's simpler that way.

Unfortunately, in Python, whenever you try to render a datetime "aware" by using the provided conversion method (`astimezone()`) it will assume the naive datetime is in local time zone, not UTC.

The datetime module provides `timezone.utc` to be used whenever you want to have datetimes _in utc_, but it needs to be explicitly used by the programmer.
