Defined by FIDE (Appendix C) as a game where all the moves must be made within a set time of less than 15 minutes for each side. They are always played with clocks. Some special rules are required. Players need not write down the moves; touch & move does not apply. Instead, a move is completed only when the player starts the opponent's clock. There is usually a provision for a player to stop the clock and claim a draw when there is no way for the opponent to win. Wins on time must be claimed by the player; games are drawn if both flags fall.
