Semi automated support for Leap Seconds is built-in until 2034.
The operator programs in a UTC date and UTC time at which the Leap Second event is required.
On this date, at this time, a Leap Second is automatically added. International convention is that
Leap Seconds are added, so the time sequence is:
• 23: 59: 59 UTC
• 23: 59: 60 UTC
• 00: 00: 00 UTC
• 00: 00: 01 UTC
In a television station, 00:00:00 UTC might be in the middle of your busy schedule. If this is so,
you can choose another UTC time at which to action the Leap Second; for instance at
02:00:00 UTC the following morning. Only the date and hour at which the Leap Second
occurs is programmable. These dates are input as UTC so you may have to take account of your
time zone and daylight saving status.
Once the Leap Second event occurs, all the subsequent timecodes are recalculated so that they
will also have moved by one second. Subsequent Leap Seconds can be added by the operator as
they are announced.
