What are the Game Timekeeper's duties?

Rule 5.7 of the Hockey Canada Playing Rules 2026-2028 says the Game Timekeeper:

• records the start and finish time of each game and all actual playing time during the game;
• signals the referee for the commencement of the game, the start of the second and third periods and each overtime period;
• if the rink has no automatic sound device, or it fails, signals the end of each period, each overtime period and the end of the game with a siren or whistle;
• announces, or has announced, when ONE MINUTE of actual playing time remains in each regulation or overtime period;
• refers any dispute about time to the referee, whose decision is final.

Equipment (Rule 1.12): each rink must have a suitable sound device for the Game Timekeeper and a clock showing the time remaining. Where clocks have four faces, the face directly in front of the Game Timekeeper governs. Where a synchronized electronic buzzer or bell and green light are installed, a goal cannot be scored when the green light is showing.

Before the game starts, the referee checks that the Game Timekeeper, Penalty Timekeeper, Official Scorer and goal judges are in position (Rule 5.2 (f)).
