Penalty for Delay

[Rick Durkee]

Officials warn Team A for delay for interfering with the ball after a goal. Later, Team A delays by not having the court ready to play following a time-out. Officials should assess a Team Technical for the second instance of delay. However, the officials (for whatever reason that I understand should be prevented) do not realize it is the second delay by Team A. From reading Rule 10-1, I assume that the officials must assess the technical at the time the second infraction occurs. Do I assume correctly, or can the penalty be assessed when it is discovered? If officials must assess the penalty at the time of the infraction, when does the time to assess the penalty expire?
