If you crunch the maths on the timestamps, I am sure you could have worked it out.
Delta is simply the difference between the current packet and the previous packet in the stream.

Skew is a measure of how late (or early) the current packet is for the total conversation (relative to the nominal 
packet rate). So if the packet rate should be 50 pps and say the 1000th packet of the conversation arrives 20.03 
seconds after the 1st then the skew for that packet would be -30ms
