Within the scope of a Wireshark dissector, Is it possible to detect out order sequence ids (based on arrival time) in PTP V2?

Is it possible to detect out order sequence ids (based on arrival time) in PTP V2?

This would be for both file open and streaming pcaps, and the ordering would also be based on packets that share a "flow" direction (based on the "class" of message_id they belong too as well. I am attempting to do this at the PTP dissector level, but due to overall design philosophy of the role of a dissector, I am not sure detecting sequence id discontinuity at the dissector level is even possible. My current approach is two stored the needed info for each packet in message_id grouped sets of linked lists that can are sorted by arrival time and then waked through to check for discontinuity in the seq_ids.
