Description
Displays the PTP Transport Protocol used. In the
current implementation, PTP runs over UDP/IPV4
Indicates if the current PTP Master supports UTC
timescale, that is, if it reports the number of leap
seconds between the UTC timescale ("Earth time")
and the TAI timescale ("Atomic time").
Offset, in seconds between UTC and TAI.
Timescale used to report time values. If using UTC
(and the PTP Master supports it), the camera will
compensate for leap seconds.
Arbitrary or TAI (Temps Atomique International).
Coordinated Universal Time
Specifies the IEEE1588 servo status.
The servo is accumulating statistics on the PTP
master clock.
The servo is adjusting (synchronizing) to the
master clock.
The servo state is currently not applicable.
Clock drift, in ns per second, between the camera
and the PTP master, currently being compensated
by the camera.
Used when the camera is running as PTP slave.
The PTP Sync History is the number of of recent
PTP Sync messages kept in memory. If the history
contains less than the ptpSyncMinCount non-
outliers, the PTP servo algorithm will revert back
to the Synchronizing state.
Minimum number of non-outliers in PTP Sync
History.
Specifies the outlier threshold (in μs). When the
camera receives a PTP Sync message from the
PTP Master, if it indicates a clock offset between
the two clocks higher than the threshold, an error
caused by variations in network transmission time
for the PTP Sync packet is assumed, and the
message is considered an outlier and ignored.
This situation can happen when using Ethernet
switches that do not operate in 'PTP Transparent'
mode.
