20. TIMING AND THE END OF PERIODS
20.1 – Stadium clocks
If there are one or more visible game clocks, they will be official.
(It would be silly for officials not to use a clock that is visible to
the players, coaches, spectators and their colleagues.)
To be considered visible, at least one clock must be visible from every
spot on the field of play.
If not, the stadium clock(s) will not be used.
If there are visible play clocks, they will be official.
To be considered visible, there must be play clocks behind each end
line, at least one of which is visible to the quarterback from every
point in the field of play inside the hash marks.
If not, the stadium play clocks will not be used.
In most circumstances, the stadium clock operator(s) should be able to
start and stop the clock more accurately than anyone on the crew.
He/they should have nothing else to do.
Keep your watch in approximate time with the stadium clock.
The main reasons for doing this are:
in case the stadium
clock suddenly goes blank;
in case the stadium clock operator forgets to start or stop it, and as
a consequence a significant amount of time is lost or gained.
You are responsible for checking that the stadium clock starts and stops
when it should.
Other officials in a better position to view the clock may help you.
This is most important if the game clock is behind you.
Discuss in the pre-game who is going to do this.
Small errors in timing should just be ignored.
A few seconds here or there, especially early in a period, are unlikely
to bother anyone.
Even at the end of a half, an error of a second or two may not matter
unless it denies a team an opportunity to score, or gives them an
opportunity they should not have.
Corrections to the stadium clock should only be made when there is an
important or obvious error.
An error of less than one second per minute remaining in the quarter
should be ignored (e.g. an error of five seconds can be ignored if there
are more than five minutes remaining).
When a correction is necessary, it should be made before the next play
If an error is not corrected promptly, ignore it and carry on.
If the visible clock is malfunctioning (or in very extreme cases, if
clock operator is completely incompetent), the Referee should order
it to be switched off.
Don't ruin a good game by splitting hairs about the time.
It will make you look over-officious, especially if you do it
20.2 – Two-minute warning
If the rules provide for it, notify the Referee to issue the two-minute
warning when the ball is dead and
two minutes or less remain in the half.
(Exception: If a touchdown has been scored on the previous play the
two-minute warning will be given after the try.)
At the appropriate time, blow your whistle, stop your watch and signal
Notify the Referee that it is the two-minute warning, and inform him of
the exact time remaining.
Announce the two-minute warning and signal it to both
sidelines using the TV/radio timeout signal [S4]
Ensure that the on-field
captain and Head Coach of each team have been informed of
how much time remains in the half, not just that it is the two-minute
If the clock was stopped to issue the two-minute warning it must be
started again when the ball is next snapped (or after a free kick).
20.3 – Each period
Near the end of each half, ensure whenever the clock stops that all
officials are kept informed of the time remaining.
By rule, unless there is a stadium clock, after the two-minute warning
in each half, check that the on-field
captain and Head Coach of each team is informed
of the exact time remaining each time the clock is stopped
Responsibility for ruling whether the ball is snapped before or after
the period ended:
If there are no stadium clocks, the on-field timekeeper is responsible.
If his watch does not have an audible or vibration
alert, he should raise it in front of his eyes so that he can monitor
play and the time concurrently.
If there are stadium clocks, the on-field
timekeeper should remind the Referee and Umpire that they are responsible.
If there is a clock behind
each end zone, the primary responsibility rests with the Referee.
If there is a clock behind
only one end zone, the responsibility rests with whoever is facing it.
If the clock is behind neither end zone or it is
out of the Referee and Umpire's normal view, an appropriate official
has the responsibility.
Which official this is should be determined in the pre-game conference.
When time expires, blow your whistle if the ball is dead.
Other officials should assist in relaying a ball
to the Referee in order that he can signal the end of the quarter.
20.4 – First and third periods
Go to the succeeding spot and record (in writing) the yard line on which
the ball is placed, its lateral position, the number of the next down
and the distance to the line to gain.

on which the
ball is placed, the number of the next down and the distance to the line
Once you have recorded these
details, grasp the chain and the clip, and keeping hold of it, reverse
the chain and move it and its crew to the corresponding yard line in
the other half of the field.
The down box should be moved to its new position at the same time
(under the supervision of the Side Judge, if there is one).
Supervise the down box operator in moving the down box to its new

a pressing reason to do so (e.g. weather or a previous delay to the
When the field is clear of players and coaches, signal the start of the
by giving the start the clock signal [S2].
Start your watch on this signal.
If there is a stadium clock, it too should be started and shall count
down the time remaining in the intermission.
Maintain possession of the game balls during the intermission.
Not more than five minutes before the end of the intermission, visit each
team (in the place where they have spent the intermission, if necessary)
and establish the options for the second half.
Go first to the team having first choice of option in the
second half, and then their opponents.
Ensure that both teams know who is kicking off and which goal each team
The other officials should go directly to the field and ensure that the
chain crew, alternate crew and ball boys are present.
The responsible official(s) shall ensure that the game balls are taken
back to the field.
[IN xx0 FORMATION (4-MAN CREW)]
[IN xx1/xx3 FORMATION (5/6C/7/8-MAN CREW)]
