I need a simple way to capture reactions times associated with an
onscreen event. The user sees a display, responds via click (or
verbally). I need to get the time the event displays , along with
the time that the user responds via mouse click (or verbally). I
need the times in msecs so that I can calculate the user's reaction
time.
I could use some suggestions about how to do that. The only
documentation that I have mentions NSCalendarDate which doesn't seem
like the correct path to me.
See the -timestamp method on NSEvent.
