Maximum autonomy when synchronization is lost
►
If the time source is lost, the server can function autonomously. When the autonomy
time is exhausted, the server stops providing time to its outputs. The autonomous
operation time can be set here or replaced by “-1”, “disable” or an empty field to disable
the autonomy limit.
Manual setting of the leap indicator
►
Allows you to tell the time server that a leap second is announced on the following 31
st
December or 30
th
June so that it can apply the second at the right time and issue a leap
second indicator (LI) to its NTP and DCF outputs. This indicator will be active one day
in advance for NTP and one hour in advance for DCF and will be automatically rest on
1
st
January or 1
st
July.
►
When “Unset” is selected, the time server uses the information received from its time
input. In this configuration and without any information received from its time input it
does not apply a leap second and emits the “Unknown (unsynchronised)” indicator.
Some NTP clients refuses to synchronise when the indicator is
“Unknown (unsynchronised)”.
Note: if the server no longer has a synchronisation source but still has enough battery life left, or is
configured to be in free running mode, it will inset the programmed leap second and reset the indicator.
►
Return to "No additional second"
➔
After the leap second is applied, the indicator is
automatically reset to “Unset” by default. Check this box to reset the indicator to “No
additional second” instead of “Unset”.
