MySQL 服务器记录的条目与系统或 mysql 本身的时间不同：

mysql> select @@global.time_zone;
+--------------------+
| @@global.time_zone |
+--------------------+
| SYSTEM             |
+--------------------+
mysql> select NOW();
+---------------------+
| NOW()               |
+---------------------+
| 2016-02-24 10:47:30 |
+---------------------+

2016-02-24T18:47:30.503214Z    2 Query  select NOW()

时间戳似乎与日志同步：

mysql> show variables;
timestamp               | 1456339753.062182 # 18:47
log_timestamps          | UTC
