If DateTime::from_timestamp(0, 0) fails (which is extremely unlikely), it falls back to the current time, making it inconsistent with the documented behavior of using Unix epoch as a fallback for data corruption. Consider using DateTime::from_timestamp(0, 0).unwrap() or a more explicit error handling approach.
