Installation, Operation and Administration

Overview

Clock Locking prevents the time or date from being changed from within Windows. The clock locking feature allows you to lock down the date and time to prevent it being changed by people or programs.

When activating Clock Locking in ClockWatch for the first time, you will be asked for the administrative password. This password is used to unlock ClockWatch from the System Tray when it is running in the lock-down mode.


In the lock-down mode the program continues to run hidden in the desktop. Its system tray icon is invisible – the regular ClockWatch clock face is replaced by a (gray) empty space in the system tray. Passing the mouse over the area will give an “OK”. Right clicking the mouse over the area will bring up the enter password screen, the gateway back into the ClockWatch application.


Notes:

  • ClockWatch Sentry Pro can continue to set the correct time through external synchronization even when the clock is locked.

  • Every attempted date or time change is logged in the event log.


Installation

Operation

Clock Locking in Operation -

1.      Someone tries to change the time from the Windows control panel or another Windows application.

2.      ClockWatch Sentry detects the change and sets the clock back to its original time (within half a second).

3.      The unauthorized time change attempt is added to the event log (Program Files/Beagle Software/ClockWatch/eventlog.txt) specifying the date and time of the time changing attempt, the time it occurred and the time the clock was trying to be set to.

  4. Open the file, eventlog.txt, by double clicking.

Sample log file entry:

Date     Time      Type    Action
-----    ----      ----    -----

This entry warns that at 18:03 on 2/21/03 someone tried to change the time to 19:00

 

The Sentry Monitor Application

  1. ClockWatch Sentry includes a hidden monitoring application that ensures that ClockWatch Sentry is running.
  2. If someone tries to disable the lock by terminating the ClockWatch application the monitoring application will restart ClockWatch and reset the lock.
