>>Wait a minute, I thought of an old puzzle. A man has a grandfather clock that chimes the hours, and chimes once on the half hour. As he walks into his house, he hears it chime once. A half hour later he hears it chime once. Another half hour later he hears it chime once. Yet another half hour later he hears it chime once. Thinking it is broken, he decides to go to the clockmaker and and he is leaving he hears the clock chime once. The clockmaker explains that the clock is functioning correctly. Why?

>Sorry to jump in, but how about: He walks in at 12:30 am and hears the half hour chime. then a half hour later, he hears the 1:00 am chime. Half hour later, the single 1:30 am chime. Then, sometime before the 2:00 am chimes go off, one of the servants (he does have servants, right?) sets it back an hour for daylight savings and he hears the 1:00 am chime again. He is just leaving the house at 1:30 am (again) and hears the half-hour chime.

I like that answer! Combining it with Barbara's answer, I guess it's possible to hear seven single chimes.
