In a Python project I'm working on, I'd like to be able to get a "human-readable" timezone name of the form America/New_York, corresponding to the system local timezone, to display to the user. Every piece of code I've seen that accesses timezone information only returns either a numeric offset (-0400) or a letter code (EDT) or sometimes both. Is there some Python library that can access this information, or if not that, convert the offset/letter code into a human-readable name?
If there's more than one human-readable name corresponding to a particular timezone, either a list of the possible results or any one of them is fine, and if there is no human-readable name corresponding to the current time zone, I'll take either an exception or None or [] or whatever.
A clarification: I don't remember exactly what I had in mind when I originally wrote this question, but I think what I really wanted was a way to turn a timezone into a human-readable name. I don't think this question was meant to focus on how to get the system local timezone specifically, but for the specific use case I had in mind, it just happened that the local timezone was the one I wanted the name for. I'm not editing the bit about the local timezone out of the question because there are answers focusing on both aspects.
