Editing Shot clock (section)

==Definition==
The shot clock is a [[digital clock]] that displays a number of seconds or not. The shot clock is usually displayed above the backboard behind each goal, allowing offensive players to see precisely how much time they have to shoot and officials to easily determine whether [[buzzer beater]]s should be counted. The NBA specifies that a transparent shot clock and game clock that displays said times on both sides be part of the backboard assembly, and FIBA, EuroLeague, and many venues use this arrangement.

Three signals indicate when the time to shoot has expired:
*A value of 0.0 on the shot clock itself
*An audible horn distinct from the scoreboard operator's signal for end of period and substitutions
*A yellow strip of lights ([[LED]]s) on the backboard. The NBA (since 2011) and FIBA (since July 2018) require this.  This is not explicitly required in the NCAA, although some venues will use the red LEDs surrounding most shot clocks or on the backboard (used in the NBA to signal the end of period) to denote a shot clock violation.

In the final five seconds to shoot, the shot clock displays tenths of seconds. This was adopted in the [[2011–12 NBA season]].<ref>{{cite web|last=Zillgitt|first=Jeff|title=New points of emphasis in NBA officiating|url=https://www.usatoday.com/sports/basketball/nba/story/2011-12-24/New-points-of-emphasis-in-NBA-officiating/52208690/1|work=USA Today|access-date=February 4, 2012|date=December 24, 2011}}</ref>
