<P> In the 1969--70 season, women's collegiate basketball (at the time sanctioned by the Commission on Intercollegiate Athletics for Women) used a 30 - second shot clock on an experimental basis, officially adopting it for the 1970--71 season . Unlike the women's side, there was initial resistance to the implementation of a shot clock for men's NCAA basketball, due to fears that smaller colleges would be unable to compete with powerhouses in a running game . However, after extreme results like an 11--6 Tennessee win over Temple in 1973, support for a men's shot clock began to build . The NCAA introduced a 45 - second shot clock for the men's game in the 1985--86 season, reducing it to 35 seconds in the 1993--94 season and 30 seconds in the 2015--16 season . </P> <P> From its inception in 1975, the Philippine Basketball Association adopted a 25 - second shot clock . This was because the shot clocks then installed at the league's main venues, the Araneta Coliseum and Rizal Memorial Coliseum (the latter no longer used by the league), could only be set at 5 - second intervals . The league later adopted a 24 - second clock starting from the 1995 season . The Metropolitan Basketball Association in the Philippines used the 23 - second clock from its maiden season in 1998 . In Filipino college basketball, the NCAA Basketball Championship (Philippines) and the UAAP Basketball Championship adopted a 30 - second clock; they switched to 24 seconds starting with the 2001--02 season, the first season to start after the FIBA rule change in 2001 . </P> <P> In the NBA (since 1954), Women's National Basketball Association (since 2006), and FIBA play (since 2000; 30 - second from 1956 to 2000), the shot clock counts down 24 seconds, thus often being called the "24 - second clock ." If a shot is attempted and hits or enters the rim, or if the defensive team gains possession via a rebound, steal, or out - of - bounds play, the shot clock resets . Failure by the offense to attempt a shot that hits the rim within the prescribed time results in a "shot clock violation" and a loss of possession to the other team . Three signals indicate when the shot clock expires--a shot clock signal, illuminated lights on the shot clock (NBA, FIBA, Euroleague, and many venues using an NBA - style transparent shot clock), and in the NBA and Euroleague only, a yellow LED light strip on the backboard . In the 2011--12 NBA season and 2014--15 Euroleague, the last five seconds of the shot clock were modified to include tenths of a second, allowing offensive players to see precisely how much time they have to shoot and officials to determine any last - second shots easily . In the 2016 - 17 NBA season, a new' official timekeeper' deal for the NBA with Swiss watch manufacturer Tissot introduced a new united official game clock / shot clock system, putting both timing systems under the same system for the first time . Tissot also became official timekeeper for the WNBA in the 2017 season . </P> <P> Furthermore, the shot clock is not reset on a foul in the frontcourt . Rule changes in the NBA since 1998, and in FIBA after 2010 state the shot clock will be reset only if 13 seconds or fewer are on the shot clock, after which it is reset to 14 seconds . </P>
