Changes between Initial Version and Version 1 of Ticket #34659

-              initial
+              v1
 To test whether a mysql server has the zoninfo database loaded (feature name: `has_zoneinfo_database`), the [following code](https://github.com/django/django/blob/1fe0b167af3611cca79e8a8092ee929312193c6f/django/db/backends/mysql/base.py#L410) is run:
+```
+{{{
 CONVERT_TZ('2001-01-01 01:00:00', 'UTC', 'UTC') IS NOT NULL
+```
+}}}
 However, this test is not actually used (i.e. there is no condition on the feature being True) when [generating sql](https://github.com/django/django/blob/main/django/db/backends/mysql/operations.py#L94), despite the fact that the generated sql contains something that we know will evaluate to `NULL`
 …
 This shows up when filtering like so:
+```
+{{{
 Foo.objects(some_datetimefield__date="2023-06-16")
+```
+}}}
 which evaluates to the empty queryset, despite there being such objects. `USE_TZ = True`, obviously
