S-COM 7K - Adjust Clock Seconds

Clock and Calendar
8-7
Adjust Clock Seconds
Forces the clock to add or subtract seconds.
• This command simplifies the periodic synchronization of the clock without a
time reference.
• This command is usually used with the Scheduler to allow the controller to
adjust its own time.
• Don’t use this command between 11:59 PM and 00:01 AM. Otherwise, the
time will be adjusted, but the day will be wrong.
• Use the Message Run-Time Variable 9816, “Seconds, CW”, or 9832
“Seconds, male voice” to check the amount of correction required.
• If you are using the Scheduler to automatically subtract seconds from the
clock, use the version of the Subtract Clock Seconds command with the
inhibit. This prevents the scheduler from executing the command more
than once.

Example:
Using the Scheduler, the accuracy of the clock over long periods of time can be
improved. To know how much adjustment will be required, use the Reset
Clock Seconds command to manually synchronize the clock to a time
reference. A week later, enter the command to speak the seconds, for
example:
(PW) 15 9832 *
