3.26.3
The NTS-100 will automatically determine the next available date for a leap second. The
Up and Down arrows can be used to scroll between None, +1, and -1. A setting of “+1”
will cause a second to be added to the end of June 30, 1996. A setting of “-1” will cause
a second to be subtracted from the end of June 30, 1996. A setting of “None” will not
effect the time. Press "FUNC/ENTR" to enter the new value, “CLR” to return the original
setting, or “STATUS” to exit function 67 without changing the previously stored
information.
