Settings OptionsTab

This tab allows users to select the mode ClockWatch system will work under. The modes available include Manual, Once, Daily, Periodic and Auto.

Setting Modes

Manual

Provides for on demand settings only. Use the Set Time button to make a time setting at any time. The timeserver used will be the one you specify under the Server option tab.

Once

Used to schedule a single setting in the future. The date and time of this scheduled setting is shown in the Timeserver/Time setting display window (middle window).

Daily

Used to schedule a setting at the same time once a day. Once specified, ClockWatch will attempt to make a setting each day at that time if the program is running.

Periodic

Used to schedule settings with fixed timed intervals between settings. This provides for a setting to be made at a specific time interval - once every hour, 8 hours, 2 days, etc.

Auto

The program determines when to make the next setting based on the accuracy of previous settings and the accuracy level desired.  Using information from the last setting where the clock was changed, ClockWatch determines when the next setting needs to occur to maintain the accuracy you've selected.  For example, if your computer loses time at the rate of 2 minutes per day and the desired accuracy is one minute per day then ClockWatch will make a setting at least* every 12 hours.

* Since the rate of loss is not constant for most computers, an uncertainty factor is used in making the scheduled time calculation.

Usage Notes:

  • For a setting to be attempted, ClockWatch must be running and the computer must be connected to the Internet, unless direct modem connection is used.
