stamp_packet()

std::vector< uint64_t > fsw::time::BoardClockSync::stamp_packet	(	const std::string &	board_key,
		uint64_t	arrival_ns,
		const std::vector< uint32_t > &	chunk_ms )

Stamp one packet's chunks for one board.

Parameters

board_key	stable identity of the source board (source IP)
arrival_ns	server receive time of the packet (epoch ns)
chunk_ms	the packet's chunk timestamps in send order (board uint32 millis; may wrap mid-packet)

Returns

one epoch-ns timestamp per chunk, same order as chunk_ms
