The race timer is responsible for the following duties:

(1) Recording accurately the time elapsed between the start and finish of each race. The time will be recorded from the instant the race begins until the first horse reaches the finish line. (As a backup to the electronic timer, the race timer will also use a stopwatch to time all races. In time trials, the race timer will ensure that the board of stewards approves three designees to use at least three stopwatches.)

(2) Posting the official running time on the infield totalisator board at the end of each race. (At a racetrack equipped with an appropriate infield totalisator board, the timer will post the split times for races in fractions as a race is being run. For quarter horse races, the timer will post the official times in hundredths of a second.)

(3) Maintaining a record of fractional and finish times of each race. The record will be available for inspection by the board of stewards.
