configured as a Stratum 2 server then it will show the IP address of the
upstream Stratum 1 server.
Offset
This field shows the offset in seconds between the NTP system clock and the
GPS Subsystem clock. Positive implies that the NTP system clock is ahead of
the GPS Subsystem clock.
Leap Indicator
This field shows whether a leap second is pending. Leap second events occur
Bits
