MySQL:Как да избера UTC отместването и DST за всички часови зони?

Опитайте тази заявка. Времето на отместване е (Отместване / 60 / 60)

SELECT tzname.`Time_zone_id`,(`Offset`/60/60) AS `offsettime`,`Is_DST`,`Name`,`Transition_type_id`,`Abbreviation`
FROM `time_zone_transition_type` AS `transition`, `time_zone_name` AS `tzname`
WHERE transition.`Time_zone_id`=tzname.`Time_zone_id`
ORDER BY transition.`Offset` ASC;
