测试程序的时候，我把当前时间往后加了一天，mysql还是正常启动的，tomcat也正常运行，但是当我重新登录的时候，会报一下错误：
- Java code

不调时间一切都正常啊，这是怎么回事？我在网上查说是socket链接没有关闭，程序中没有用啊，疑惑中。

可能是mysql版本的一个bug.
试试5.0.18
http://lists.mysql.com/java/8667
I reinstalled msyql-5.0.18, after that the problem disappear. I think that is a bug in mysql 5.0.16.
重新安装mysql, 新版本.
另外, 学会用google, 那里可以给你很多非常多太多的答案!!!

你和时间和数据库服务器时间不一致吧?
是不是你数据库放在别的电脑上?
