QuestionHow do I manually configure a leap second in SecureSync and NetClock 9400
AnswerIn the nominal case of using GPS to synchronize the SecureSync or NetClock 9400, no user intervention is required to make these products leap-second-aware. The timing engine receives a leap second indicator through the GPS broadcast in order to resolve it appropriately in all generated signals. In the case of long periods of GPS outage, or an alternative reference signal is used that does not pass leap second indication into the timing system, then you can use the web-based graphical user interface to add it manually.
See the topic Configuring a Leap Second in the user manual.
In general, the leap second offset is +1 and the date and time is the day after UTC midnight @ 00:00:00. So if the leap second is positive at UTC midnight on December 31, 2016, then the date and time is 2017-01-01 00:00:00.
