You are locked in a jail cell with no windows. and you need to tap out a message on the wall for the man in the other cell next to you. The problem is that you have to do it at exactly 9:15 PM, when the guard outside is switched, so your noise won't be noticed. You can't hear the switching of the guards through your walls, and you have no clock.
There is a faucet with water dripping very consistently from it in the corner, but you don't know if it is dripping at 30 or 40 or however many drops per minute, and that wouldn't give you the time in any case. You can just make out the chiming of a church bell, but it chimes just once at the top of each hour, so you can't tell the time from that. You can feel the wall facing west start to cool after the sun sets, but you don't know what time the sun is setting, and this isn't very precise in any case. Your dinner is always passed into your cell between 6:15 and 6:45. How do you determine when it is exactly 9:15 PM?

After dinner arrives, you listen for the church bell. Since dinner comes between 6:15 and 6:45, the next chiming has to be at 7:00 PM. When you hear it, you start to count the drips from the faucet until you hear the chime again at 8:00 PM. Divide the number of drips by four, and you'll have the number of drips that fall in fifteen minutes (Or you can divide by sixty to get the drops per minute, and then multiply this by fifteen). When the bell chimes again at 9:00, you start counting drips until you reach the specified number. It is now 9:15 PM, and time to tap out your message.

1. Listen for the church bell and then count the number of faucet drips until the next church bell sounds.
2. Take the number of drips in one hour and divide it by 4.
3. Wait until your dinner is brought to you and then listen for the third bell to ring after your dinner is there, this should be the 9pm chiming.
4. Count the number of drops from the faucet that you figured up in step 2. This is one quarter of one hour or 15 minutes, that would make it 9:15pm.
