First you need to be running something, prolly gpsd with PPS, that is
generating time stamps to SHMs.
Second, dump the SHMs to a log, one minute data to start:
ntpshmmon > ntp.log &
sleep 60; killall ntpshmmon
Third, pull into ntpshmviz:
ntpshmviz < tnp.log
Note, you can not pipe the data, it must be in a file.
