#當(dāng)前時(shí)間減30分鐘
SELECT (NOW() - INTERVAL 30 MINUTE) AS newTime;    #2021-05-20 14:02:26
#當(dāng)前時(shí)間加30分鐘
SELECT (NOW() + INTERVAL 30 MINUTE) AS newTime;    #2021-05-20 15:02:41
#當(dāng)前時(shí)間減1天
SELECT (NOW() - INTERVAL 1 DAY) AS newTime;        #2021-05-19 14:33:26
#當(dāng)前時(shí)間加1天
SELECT (NOW() + INTERVAL 1 DAY) AS newTime;        #2021-05-21 14:33:33
#當(dāng)前時(shí)間減1個(gè)月
SELECT (NOW() - INTERVAL 1 MONTH) AS newTime;      #2021-04-20 14:34:10
#當(dāng)前時(shí)間加1個(gè)月

#當(dāng)前時(shí)間加1年
SELECT (NOW() + INTERVAL 1 MONTH) AS newTime;      #2022-05-20 14:35:23

#指定時(shí)間的加減，將上面的NOW()函數(shù)換為指定日期時(shí)間即可，以加30分鐘為例，如下:
SELECT ('2021-05-20 12:30:00' + INTERVAL 30 MINUTE) AS newTime;        #2021-05-20 13:00:00
