The difference between Mysql application log time and system time is eight hours

The difference between the Mysql application log time and the system time is eight hours

I take the mysql slow query log as an example. By viewing the slow query log, I found that the difference between the log time and the server system time is eight hours

reason

The system default log_timestamps is UTC, Coordinated Universal Time, also known as Universal Universal Time, Universal Standard Time, and International Coordinated Time.Due to the different abbreviations in English (CUT) and French (TUC), as a compromise, the abbreviation is UTC.8 hours difference from linux system time (local time)

Solution

Workaround

mysql> SHOW VARIABLES LIKE 'log_timestamps';+----------------+------------+| Variable_name | Value |+----------------+------------+| log_timestamps | SYSTEM |+----------------+------------+1 row in set (0.00 sec)mysql> SET GLOBAL log_timestamps = SYSTEM; (effective immediately, restart the mysql service, invalid)Query OK, 0 rows affected (0.00 sec)

Permanently resolved

Add the following line to /etc/my.cnf:

log_timestamps=systemRestart the service to take effect.
