HH:MM:SS is the hour, minute and second of the UTC timestamp of the most recent update received
from the GPS Subsystem.
+S.sssssssss is the offset in seconds between the NTP system clock and the GPS Subsystem clock.
Positive implies that the system clock is ahead of the GPS Subsystem clock.
RCVDCNT is a count of the number of NTP packets received since startup of the NTP daemon.
This is a 32-bit counter so it will wrap back to zero after 4,294,967,295 packets.
SENTCNT is a count of the number of NTP packets sent since startup of the NTP daemon.
This is a 32-bit counter so it will wrap back to zero after 4,294,967,295 packets.
SENT/sec is the current rate of NTP packets being sent per second.
DROPCNT is a count of the number of NTP packets dropped since startup of the NTP daemon.
This is a 32-bit counter so it will wrap back to zero after 4,294,967,295 packets.

oscctrlstat
This command displays the current values of the system oscillator control parameters. These param-
eters are related to the disciplined system oscillator. The command formats the data and prints this
fixed-length string having these fields:
YYYYMMDD.HH:MM:SS LKSTAT COAST ESTERR MEASERR TIMEDEV AGERATE TAU EFCDAC TEMP
Where:
YYYY
is the year of the UTC timestamp of the most recent update received from the
GPS Subsystem.
MMDD
is the month and day-of-month of the UTC timestamp of the most recent update
received from the GPS Subsystem.
HH:MM:SS
is the hour, minute and second of the UTC timestamp of the most recent update
received from the GPS Subsystem.
LKSTAT
is the GPS Subsystem control status, either WRM (warming up),
ACQ (acquiring), LKG (locking) or LKD (locked).
COAST
is the number of seconds the GPS Subsystem has been in coast mode
(unlocked to GPS).
ESTERR
is the estimated time error of the GPS Subsystem when in coast mode, in
seconds.
