DATE002warningPro

naive-datetime

Creating datetime without timezone information.

Applies to: Python

Why this matters

Naive datetimes (without timezone) cause bugs when your app runs in different timezones or when comparing times. Always use timezone-aware datetimes. Use datetime.now(timezone.utc) or datetime(..., tzinfo=timezone.utc).
