ClockWatch Sentry
Prevents unauthorized users from changing the system date or time

Stops time card fraud!

Whenever an unauthorized user tries to change the date or time, ClockWatch Sentry blocks the change and logs the attempt. Someone trying to change the time from the Control Panel or another application won't be able to change either the date or the time of the computer.

ClockWatch Sentry is ideal for averting potential fraud or tampering situations, such as electronic timecards, time and attendance systems or other computer time tracked events.

Sentry is available in two versions.
Sentry Basic is for those who only need the protection of Clock Locking while ClockWatch Sentry  Pro includes the ability to sync the computer with the Atomic Clock, making sure the computer's clock is correct.


 If you are looking for a time stamp with atomic clock accuracy consider our DocuClock.
