[3.13] gh-117398: Add multiphase support to _datetime by ericsnowcurrently · Pull Request #119694 · python/cpython
This is an unrevert of d58ebf0 (gh-119636), which was reverted by 9216a53 (gh-119639) due to problems which have been resolved.
This is minimal support for multiphase init. Subinterpreters are not supported yet. That will be addressed in a later change.
(cherry picked from commit 3e8b609)
