Timing instant challenges

It works best for the team manager to use a kitchen timer that beeps when the time is up. The team is responsible for keeping track of how much time is left and may appoint one team member to be the timer and wear a watch for this purpose or check the TM's timer. The team may also ask the TM or appraiser how much time is left at any time. During the tournament, an appraiser may indicate when there is one minute left of the preparation time in the instant challenge. A TM can do this but the team must realize that at the tournament the appraiser is not required to tell when a minute is left.
