- [nitpick] Consider extracting the magic number 500 into a named constant to clarify its significance and improve maintainability.
get_current_millis() as i64 - self.born_time as i64 - self.poll_time as i64 > 500

Ensure that casting to i64 does not introduce negative values in cases where the current time is less than the sum of born_time and poll_time; consider using saturating subtraction if negative differences are not expected.
