Work Time Monitor is a free application that keeps track of the time spent working on the computer and automatically generates time reports, allowing you to easily calculate your monthly work time.

Work Time Monitor logs your work start and end times automatically by measuring the active and idle durations over a 24 hour period. It is suitable for use with desktop computers, which are idle during non-work hours. Portable computers, which may sometimes be active during non-work hours, prevent Work Time Monitor from correctly calculating the work time. For this reason, Work Time Monitor cannot be used with portable computers.
