原文：

Mysql Server processlist shows negative value(-) in connect column for system user

Some times process list out put show negative value like bellow :
Command :

watch /usr/local/mysql/bin/mysqladmin -ppass processlist

8 | system user | | Connect | -1247 | Has read all relay log; waiting for the slave I/O thread to update it |

One of the reason :
make sure both Server has same time zone.
if there is any time difference between 2 server the replicate client show negative values

翻译：

在Slave备库上查看

show processlist;

显示的SQL线程运行时间是负数（negative value）：

8 | system user | | Connect | -1247 | Has read all relay log; waiting for the slave I/O thread to update it |

具体原因待确认。
