TimestampDiff()

Batching: Batching natively supported
Ports: 1 input, 1-2 outputs

DESCRIPTION§

Compute the difference between the recorded timestamp of a packet using RecordTimestamp and a fresh timestamp. Computations are performed only for numbered packets, either by a NumberPacket element or an external entity.

Arguments:

• RECORDER — Instance of RecordTimestamp that provides the initial timestamp.
• OFFSET — Integer. Offset in the packet where the timestamp resides.
• N — Size of the reservoir. Defaults to 0.
• MAXDELAY — Integer. Maximum delay in milliseconds. If a packet exhibits such a delay (or greater), the user is notified. Defaults to 1000 ms (1 sec).
