Settings
“Settings”
provides
a dialog box to configure the “
Plura
TimeSys” service and the monitor
program:
•
“Use
of not sync LTC”:
How to use an LTC which has not been marked by the generator as
being synchronous to the real time, or if there is no information about that available. There
are three ways for the “
Plura
TimeSys” service to react:
−
“Use always” ac
cepts the LTC at all events, irrespective of having been marked as being
synchronous or not.
−
“Use if once sync” waits from the start of the system until the LTC will b
e once marked as
being synchronous. Then, the LTC will always be accepted, even if it was marked
occasionally as being not synchronous, e.g. due to reception problems. Having selected
this setting, the LTC generator is expected to be more stable than the system time even in
the free run mode.
−
“Use never” accepts the LTC only if it was marked a
s being synchronous. If not, no
readjustment will be made for a while.
•
“Difference for
ha
rd set”:
The difference between system time and LTC which will produce a
hard set on the LTC. This value can be entered with an accuracy of 1/100 seconds. Any
difference below this value will be readjusted by moderating or accelerating, respectively
the system time. By setting this value 0.00 no hard set will be made, any differences will
then be readjusted.
Such setting is of special importance in the event of leap seconds. If such differences shall
be readjusted, the value has to be set 0.00 or to 1.20 minimum; shall they produce a hard
set of the system time, select a value within 0.50 and 0.80.
