Leap second
The leap second is to compensate for deviations from the universal time (UT) which is
astronomically determined and the “International Atomic Time (TAI).
“1 second” may be added (deleted) once a year or every few years.
Automatic leap second reception function
A leap second is automatically added by receiving “leap second data” from GPS signals
at the time of leap second addition (delete).
*
“Leap second data” includes information about future leap second addition and current leap second data.
Receiving Leap Second Data
When GPS signal reception (automatic time adjustment, manual time adjustment, or time
zone adjustment) is performed on or after June 1st and December 1st, leap second data
may be received.
*
No particular operation is required.
After the completion of time adjustment (automatic time adjustment or manual time
adjustment), up to 18 minutes may be required until receipt of leap second data is
complete. Confirm the result (success or failure) of the leap second data.
→ Check whether leap second data reception was successful P. 27
When GPS signals are received under the following conditions, the leap second data
reception is also started.
• GPS signals have not been received for a long time
• Leap second data reception has failed
With
GPS signal reception, leap second data reception will be performed again. This will
continue until leap second data reception is successful. Confirm the result (success or
failure) of the leap second data reception.
→ Check whether leap second data reception was successful P. 27
