Jitter and delta is determined by the time stamps of the packets received. Some deviations are expected on the network. That why you have jitter buffers. If you put time and delta in the first 2 columns it is easy to follow how Wiresharks makes the calculation.
Take the sample PCAP file from https://wiki.wireshark.org/uploads/__moin_import__/attachments/SampleCaptures/sip-rtp-g711.pcap Set Colum 1 to be Number, Column 2 to be time (I prefer time of day as default) Column 3 to be frame.time_delta Column 4 to be rtp.timestamp
Then it pretty much explains itself.
