A system and method for delivering data packets in an electronic interconnect comprises a talker device that transmits one or more data packets over a transmission path to a listener device through one or more bus bridges that each couple adjacent busses in the electronic interconnect. Each data packet includes a time stamp that indicates when the corresponding data packet is scheduled for presentation to the listener device. An initial bus bridge preferably creates a marker packet that is propagated through the transmission path to record delay information corresponding to delay elements such as the intervening bus bridges. A final bus bridge may then utilize the delay information from the marker packet to update the time stamps of the data packets to thereby incorporate the total propagation delay of the transmission path.
