int(timezone.now().timestamp()) can differ from Django’s dateformat.format(..., 'U') behavior (notably when USE_TZ=False, where .timestamp() on naive datetimes is interpreted in local time). For consistency with the existing codepath and Django’s formatting semantics, compute the fallback using the same mechanism as the non-null branch (i.e., format timezone.now() with 'U').

Setting last_login = None in setUp() adds an extra DB write for every test in this class and makes the entire class depend on a special user state (even in tests unrelated to OIDC auth_time). Prefer moving this setup into the specific test(s) that exercise the last_login is None path, or create a dedicated user within that test to keep unrelated tests isolated and faster.

Suggested change
self.user.last_login = None
self.user.save()
