About the Clock Check Demo
The local time is taken from your local system clock. This is the time from the computer's operating system.
The standard time is taken from the server at the web site which is maintained at standard time.
The difference in seconds is the difference between standard time and local system time. Your clock is 'fast' if you are ahead of standard time and 'slow' if your clock is behind it.
The difference is given in minutes or hours depending on the magnitude.
The drift is calculated from the previous reading made from the same computer on a previous day as determined by the GMT time. Previous readings are stored locally as cookies and are recalled when the demo is run.
Drift is calculated from:
Net Difference (seconds) / Interval (days)
to give clock accuracy in terms of seconds of time that are lost (negative) or gained (positive) in a 24 hour period. The drift gives an indication of how accurate your system clock is and how often it needs to be adjusted.
Last reading shows the last time you ran the demo and a reading was stored. The demo will store only a single reading each day.
The accuracy of this test is approximately +/- 5 seconds (remember it's a demo). For a more accurate test, download and install our ClockWatch program to your computer and run it.
Unlike our ClockWatch product, the time will not be corrected on your computer.
