Clarify timezone vs “time zone”: https://github.com/python/devguide/pull/1352
Summary
The CPython PR #118449 updates the spelling of “timezone” to “time zone”. There was a discussion on the PR that the “timezone” spelling is also acceptable and have been used within the CPython docs consistently. However, both Wikipedia and The Free Dictionary redirect “timezone” to “time zone”.
Using the two-word form “time zone” would help separate the concept from the “timezone” class in Python.
The Style Guide section on CPython Devguide has
now been updated with the recommendation of using the
two word time zone when referring to the real-world time concept, and to use the one word timezone with
appropriate code markup when referring to a Python term.
