ms
Latest time deviation between
the system clock and the
received synchronization
SyOS
10000.000
s
Synchronisation correction for
any constant error in the
synchronizing source.
A positive value will
compensate a lagging external
sync and communication
delays. A negative value will
compensate any leading offset
of the external synch source.
