High Quality Content by WIKIPEDIA articles! In the National Hockey League, between stoppages of play, teams have 18 seconds (5 seconds for the visiting team, 8 seconds for the home team, 5 seconds to line up at the faceoff location) to substitute their players, except during TV timeouts. TV timeouts are two minutes long, and occur three times per period: during normal game stoppages after the 6, 10, and 14 minute marks of the period, unless there is a power play, a goal has just been scored, or the stoppage was as a result of an icing. Each team may also take one 30 second time-out, which may only be taken during a normal stoppage of play.
