For my purposes, I think that close enough is good enough--
especially if the error margin is constant. (That is, if every
time the display becomes visible the system takes the same amount
of time to get it onscreen). I'm asking a much, much lower level
question. What code do I use? I am unable to find a simple
function or Class that returns the time to the msec. For example, I
can find a "possible token in the Calendar Format String" that will
specify msecs (%F), but I have no idea how to use it.
There is always the C function gettimeofday(2)
