PC On/Off time is software that visually displays PC login and logout information, including runtime, and stores data up to three weeks. It enables you to monitor computer usage on both local PCs and networked systems.

Intended to be a timesheet tool, PC On/Off Time allows users to plan a project and check up on the progress of others. Alternatively, it can also be used at home where parents can keep a closer watch on the computer usage habits of their children. Additionally, it helps identify other problems such as ties when the PC was accidentally left on, allowing users to conserve energy and reduce associated costs.
Since the software derives information from the event logs of the PC, it does not need to be run in the background at all times and take up valuable space. With no requirement for installation, the software is entirely dependent on the event log embedded in the computer. This means that any missing information from the event log will result in incomplete data. The software currently does not record PC activities, require installation, write to the registry, or modify files beyond its own directory.
PC On/Off Time offers other versions including the Pro and Net versions. These premium versions are not limited to three weeks and perform automatic backups. They are not bound by the event log of the PC and provide complete information even if the event logs are lost or incomplete. They also allow the user to view the graphs of users on a particular network and export the log in and log off times on the PC.
Moreover, the correction of daylight savings time and lack of nag screens makes PC On/Off Time user-friendly for people looking for professional time tracking software.
