16. LEAP SECOND APPLICATION
The EC20S can apply a leap second to its UTC timescale as follows:
- In ‘Operator’ mode. The operator defines the leap second direction and the application date
using the web interface (cf. 61 and 62).
- In ‘Automatic’ mode. The EC20S gets the leap second direction and the application date
from the GNSS receiver.
Once a leap second is defined (in ‘Operator’ mode or in ‘Automatic’ mode), the NTP server updates its
leap indicator (cf. 8.2.4).
In case of a positive leap second, at the time the leap second shall be applied, the time distributed by
the Time Of Day messages on the ‘NMEA’ output has the following sequence:
… 23:59:58 …
… 23:59:59 …
… 23:59:60 …
… 00:00:00 …
