> Now, MySQL CDC connector will retrieve the offset seconds between the
> configured timezone and UTC by executing the SQL statement below, and then
> compare it with the configured timezone.
> {code:java}
> SELECT TIME_TO_SEC(TIMEDIFF(NOW(), UTC_TIMESTAMP())) {code}
> For some MySQL instances, the validating for time-zone is too strict. We can
> add 30min tolerance value.
