UTC or Local Time
Select whether the output will use a UTC or Local Time format using the 'UTC OR LOCAL TIME' radio buttons.
'LOCAL TIME' will be selected by default.

Select Extensions
Select what 'EXTENSION' will be included in the control field of the output IRIG-B signal. C37.118.1

Select Leap Second Behavior
Choose the leap second behavior from the following options:
– 'ALLOW 60TH SECOND': In the event of a leap second, the IRIG-B signal seconds counter will count an
extra second up to 60 before rolling back to 0 and incrementing the minute counter.
– 'ANOTHER 59TH SECOND': In the event of a leap second, the IRIG-B signal seconds counter will count
to 59, then will repeat second '59' again a second later, before rolling back to 0 and incrementing the
minute counter.
By default this is set to 'ALLOW 60TH SECOND'.
