The mysql.time_zone_transition table defines the exact times at which daylight saving time or other time zone transitions occur.
The mysql.time_zone_transition table is one of the mysql system tables that can contain time zone information. It is usually preferable for the system to handle the time zone, in which case the table will be empty (the default), but you can populate the mysql time zone tables using the mariadb-tzinfo-to-sql utility. See Time Zones for details.
This table uses the Aria storage engine.
The mysql.time_zone_transition table contains the following fields:
