packetSequenceNumber

PacketSequenceNumber packetSequenceNumber

Packet Sequence Number. Always incremented by one in the same channel and same SequenceVersion.

Definition at line 65 of file Defines.h.

packetSequenceVersion

UInt16 packetSequenceVersion

Packet Sequence Version.

For incremental stream, it starts with 1 at the rollout in the production environment and incremented on weekly basis or in case of failover events. For instrument definition and snapshot streams, its value changes for each new loop. its value will be rolled back to 1 if incremented beyond 65534.

sendingTime

UInt64 sendingTime

UTC date and time of packet transmission, in nanoseconds since Unix epoch (Jan 1st., 1970), with microsecond-level precision*.
