When MySQL logged slow query information to a CSV table, it stored the query_time and lock_time values with an incorrect formula. If the time was over 59 seconds, this caused incorrect statistics (either the slow query was not logged, or the time was far from correct). This change fixes the method used to store those TIME values in the slow_log table.
