I have developed an Access application that replaces the paper scoresheet
scoring for QuizBowl competitions with live, lap-top based scoring. Among
other tasks the application displays a score board that is visible to the
teams that also includes the countdown clock that times the eight-minute
halfs. I have simulated the countdown clock by using the OnTimer event for
the form with the timer set for 1000 milliseconds. The problem that I am
having is that the form that I have designed is very rich in other Events
that I must respond to, and with the huge amounts of events that I am
responding to I find that frequently other code is running for a few more
milliseconds when the TimerEvent is triggered. The TimerEvent code is
delayed in its execution multiple times during a match, resulting in my
eight-minute half actually taking an extra 2-4 seconds.
Does anyone know of a peripheral device, preferably USB2.0 compliant, which
can act as an independent timing device? Ideally this device would have
properties and methods that I could read, write and call from Access (so
that, for example, I could respond to a '0:00' event.)
If anyone can think of an alternate solution, I would be appreciative.

How about using the system clock for the time? Record the time at the
beginning of the half in a static variable. Use the TimerEvent to update
the on-screen clock, but calculate the display for your countdown from the
system clock.
Thanks for the interesting idea. I think that just might work.
