It's About Time

The information below should not be interpreted as an extension of the rules. The official rules in the Rules Manual take precedence.  This event is generously supported by the National Association of Watch and Clock Collectors. National Tournament winners received one-year NAWCC memberships and were invited to present their It's About Time device (expenses-paid trip for student and coach) at the national horology convention.

Zip file (updated!) containing computer generated MP3s with tones for all possible time trial periods.  Note each file consists of the following:

  1. An initial warning 'bell'
  2. A short delay
  3. Another warning 'bell'
  4. A short delay
  5. A start 'beep'
  6. A precise delay equal to the time in the filename
  7. A stop 'beep'

The time trial begins at the beginning of the start beep (step 5 above) and ends at the beginning of the stop beep (step 7).
