This recipe for an adapter does not work as advertised:
def adapt_datetime_iso(val):
"""Adapt datetime.datetime to timezone-naive ISO 8601 date."""
return val.isoformat()
from: https://github.com/erlend-aasland/cpython/blob/a3711d1541c1b7987941b41d2247f87dae347117/Doc/library/sqlite3.rst?plain=1#L2287-L2289
or https://docs.python.org/3/library/sqlite3.html#sqlite3-adapter-converter-recipes
If the argument has a timezone, it will produce a timezone-aware result, contrary to its documentation
Consider the difference between these:
import datetime
print(datetime.datetime.now(datetime.timezone.utc).isoformat())
print(datetime.datetime.now(datetime.timezone.utc).replace(tzinfo=None).isoformat())

"""
The recipe should instead be like this:
def adapt_datetime_iso(val):
"""Adapt datetime.datetime to timezone-naive ISO 8601 date."""
return val.replace(tzinfo=None).isoformat()
