There are three (3) twenty (20) minute periods during regulation time. One (1) five (5) minute overtime period during the regular season, and an unlimited number of twenty (20) minute periods in playoff overtime.
Assuming you are talking about general playing time, then it would require too much research and arithmetic, but a NCAA regulation basketball game is 2 20 minute periods, or halves, so 40 minutes. But there is overtime(s), which are 5 minute periods. So you have, say, Arizona vs. Oregon which is 40 minutes, and UConn and Syracuse that is 70 minutes.
Sixty minutes. A hockey game consists of three twenty-minute periods. If the score is tied at the end of the third period, the teams play a five-minute sudden-death overtime period. If neither teams score in the overtime, the game ends as a tie. In the playoffs, games cannot end in a tie. So instead of a five-minute overtime, a playoff game has an extra 20-minute sudden-death overtime period. If neither team scores, then there is another 20-minute overtime, and so on, until someone scores. There was a Detroit-Montreal game in 1956 that went to the sixth overtime, finally ending at 176 minutes 30 seconds--almost as long as three ordinary games! Detroit scored in the sixth overtime to win the game 1-0.
The same as it is now: four 12 minute quarters.
There are twelve, five second periods in one minute.
In the regular season, teams will participate in the typical five-minute overtime and then a shootout. In the playoffs, however, the teams will keep playing twenty minute overtime periods until someone scores.
7 minutes unless it goes to overtime. 3-2-2 minute periods. A match can last as long as 11 minutes with 1 minute ot, then 2 consecutive 30 second periods and repeat once more for 4 total OT minutes.

That means that the timing clock is stopped, each time the refferee blows his whistle to stop play, for a penalty, an injury, or when a goal is scored. The offcial time keeper has two stop watches that are the offcial method of keeping the games time.
