SnapTime is similar to a stop watch. The difference is, it works in absolute time.
Every time you click the SNAP button, it captures the current time and displays
it in a list. A traditional computer stop watch captures the number of seconds
since you started timing.

What is it for? After I complained about the daily time signal being late, the
National Research Council asked me to measure how delayed the CBC radio time
signal is each day by the time it gets to Victoria. I wrote SnapTime to solve
that problem, at least approximately. I can click SNAP when I hear the tone,
and then can see how many milliseconds after 10 AM it is.

I was also curious about how in sync my NTP computer clock is with my
radio-synched watch. I can use it for that too.
