How do I time quarters, intervals and a late team?

Two timekeepers officiate each match. Timekeeper 1 is the official timekeeper (match timer, intervals, stoppages) and Timekeeper 2 is the backup timer, which may be the electronic timer or scoreboard. Count-down timers should be used for all timing, and a real time clock showing seconds is also required.

• Playing time: start the match timer and electronic timer when the umpire's whistle starts play, hold time when the umpire signals play to stop (whistle, hand signal and eye contact), and restart when the umpire signals play to resume.
• Intervals (2019 manual): 4 minutes between the first and second quarters and between the third and fourth. Half-time is either 8 or 12 minutes, set by the event organiser, so check before the match. Start the interval timer as soon as the quarter finishes and reset the match timer during the interval.
• Warnings: activate the umpire alerts for the 30 second warning (32 seconds on the timer) and the 10 second warning (12 seconds on the timer). In Australia, signal that the bench is ready to start play with a discreet nod to the umpires.
• End of a quarter: as best practice in Australia, activate the umpire alerts at the same time as the siren. If no siren is used, activate them 2 seconds before the time is due to elapse.
• Late team: if a team does not take the court at the scheduled start or restart, 30 seconds is allowed. Start the 30 second timing when instructed by the umpires and activate the alerts at 2 seconds on the timer.
• Record: use the Stoppage Form to record the real time each quarter starts and ends (no seconds).
