Mysql：时区问题-时区配置

• Mysql默认使用系统的时区

mysql> show global variables like '%time%zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone |        |
| time_zone        | SYSTEM |	# 表明使用系统时间
+------------------+--------+
2 rows in set, 1 warning (0.17 sec)

mysql>

• 在Mysql配置文件中设置时区

修改完配置之后，需要重启MySQL服务，否则不生效。

[mysqld]

# 设置默认时区
# default-time-zone='+08:00'

修改之后在终端查看是否生效

mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone |        |
| time_zone        | +08:00 |
+------------------+--------+
2 rows in set, 1 warning (0.03 sec)

mysql>
# 设置新的时区
mysql>  SET TIME_ZONE = '-6:00';
Query OK, 0 rows affected (0.00 sec)
# 查看设置的时区是否生效
mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone |        |
| time_zone        | -06:00 |
+------------------+--------+
2 rows in set, 1 warning (0.00 sec)
