mysql 时区-时间转换

时区（timezone）转换函数：convert_tz(dt,from_tz,to_tz)

select convert_tz('2008-08-08 12:00:00', '+08:00', '+00:00'); -- 2008-08-0804:00:00

SELECT CONVERT_TZ(CURDATE(), '+08:00', '+00:00')

时区转换也可以通过 date_add, date_sub, timestampadd 来实现。

select date_add('2008-08-08 12:00:00', interval -8 hour); -- 2008-08-08 04:00:00
select date_sub('2008-08-08 12:00:00', interval 8 hour); -- 2008-08-08 04:00:00
select timestampadd(hour, -8, '2008-08-08 12:00:00'); -- 2008-08-08 04:00:00
