PC On Off Time

这空闲时间跟踪工具显示您的计算机一直活跃在过去3个星期以前没有要求设置的时间。该软件并不需要在后台运行，因为Windows操作系统跟踪登录和注销/待机时间（工作时间），默认情况下，方案分析。

This free time tracking tool shows the times your computer has been active during the last 3 weeks, with no previous setup required. The software doesn't need to run in the background, because Windows OS tracks logon and logoff/standby times (working hours) by default, and the program analyses it.
