[time-nuts] Collecting raw timing data

[Jeff Mock]

Thanks so much, your description of collecting the raw timing data is 
really clear.  I like the technique of doing timing interval 
measurements from a slower known reference on one channel to a DUT on a 
second channel.  This definitely gets me started.
