I tried to read it, will try again later but I wasn't really getting it. the idea would be, .astimezone() is bad, and should be something equivalent to .convert_between_timezones(from, to), where there's some convenient way for "from" to indicate "the system time zone", but you still have to be explicit that you consider this arbitrary number to be in a particular time zone.

not following why the "this is the system timezone" must be hardcoded to be an invisible assumption, as opposed to something somewhat explicit. I mean this is literally not far off from a simple namechange of ".astimezone()".
