Proposal:
Starting with Python 3.12 datetime.utcfromtimestamp will be deprecated in favor of the timezone aware datetime.fromtimestamp. https://docs.python.org/3.12/library/datetime.html#datetime.datetime.utcfromtimestamp
AFAICT this only effects one instance in the active (excluding examples) code base and the fix should be pretty simple

-    EPOCH = datetime.utcfromtimestamp(0).replace(tzinfo=timezone.utc)
+    EPOCH = datetime.fromtimestamp(0, tz=timezone.utc)

Note: datetime.utcnow() will also be deprecated in favor of datetime.now(tz=timezone.utc) but that's only used in examples or tests. https://docs.python.org/3.12/library/datetime.html#datetime.datetime.utcnow
