At Special Events
Additionally, to the moments selected at

an update with the time & date
reference can be programmed at special events:
Reference Lock within 20 min
: Due to the nature of some real
–
time sources it may last
some minutes after power has turned on until a “Lock“ status will be indicated. The
module can be set to monitor this status for a 20 minutes period after power
–
on,
and as soon as “Lock” has been detected an update occurs again. There is a risk
of generating a time jump caused by this update. If you don’t need this feature,
uncheck this checkbox. The
“Lock“ status has to be part of the status data received
from the real

Please refer to chapter “

when the real
–
time reference will be corrected through a leap second. The leap
second adjustment has to be announced in the status data of the real

reference input.

Leap Second” as well.
