Clock Adjust
Purpose
This command allows a Control Op to synchronize the time-of-day clock seconds
to an accurate time source.
Remarks
If the "seconds hand" is at less than 30, this command resets seconds to zero. If
it's greater than 30, minutes are incremented by one and seconds set to zero.
The clock has a cumulative error due to fmite accuracy and temperature drift in
its time base. This command proviqes a simple way to periodically adjust the
clock.
Example
We noticed that the clock is off by about 20 seconds. We can listen to WWV or
another accurate time source and enter the Clock Adjust command "straight up",
or right on the minute to synchronize the internal clock.
Note
If the time is in error by more than 30 seconds, the clock must be set using the
"Time of Day Set" Programming command.
