There is a 24 second shot clock in the NBA.
1950's
Players in the NBA have a 24-second grace period from the shot clock to get off a shot clock. In college basketball, the shot clock limit is 35 seconds.
In basketball, there is a 24 second shot clock. As soon as a team gets possession of the ball they have 24 seconds to attempt a shot, if they don't get a shot off within that time limit, it's called a 24 second violation, and then the ball goes over to the other team.
The blue clock is more accurate because it loses only one second every 24 hours, whereas the red clock is broken and does not run at all. This means the blue clock still maintains a fairly accurate timekeeping mechanism, despite the slight daily loss.
The red clock is more accurate because even though it is broken and doesn't run, it is showing the correct time twice a day. The blue clock loses one second every 24 hours, making it gradually fall out of sync with the correct time.

the second hand
A clock that is timed for 24 seconds. When a team has the ball they have 24 seconds to make a basket. If the 24 seconds expires it's a "shot-clock violation" and the other team gets the ball. Also if someone attempts to shoot but hits the rim, but dose not go in the shot-clock will reset back to 24. If the game clock is below 24 seconds the shot-clock will be turned off.
I had one of those: it's a 24 hour clock with a picture of the Earth (as seen from the north pole) on a disk that turns in place of the hour hand. The minute and second hands are normal.
The difference between 12 hour clock and a 24 hour clock is that when you say 1:00am for a 12 hour clock you would say 0100 hours
Unless it's a 24-hour clock, then it means it's 1pm.
