# What’s the Time?

A grandfather clock chimes the appropriate number of times to indicate the hour, as well as chiming once at each quarter hour. If you were in another room and heard the clock chime just once, what would be the longest period of time you would have to wait in order to be certain of the correct time? Assuming you had absolutely no clue what time it was.

It would seem that 12:15 to 2:00 would be the answer, but since we move the clocks back one hour at 2:oo AM for daylight saving time, the correct answer has to be two hour and 45 minutes.

• you would have to wait 2hour . if it chimed once at 1 oclock you would still wait , to hear 2 chimes

• det

1hr 30mins, without daylight saving time

• You’re correct, Det!

You would have to wait 90 minutes between 12:15 and 1:45. Once you had heard seven single chimes, you would know that the next chime would be two chimes for 2 o’clock.

Paul, in order for “daylight savings time” to come into play, you would have to manually set the clock back, which–unless you did it with your eyes closed–would indicate the time to you. Kudos for thinking outside the box! That’s what the Riddledude is all about!
