My goodness, is that the time? No, it isn't, but all the same, we must get on with your ideas about what to do with broken clocks. Rather too many readers told us that a broken clock is right twice a day, but only Len Clarke suggested setting your alarm clock for the time it reads, so that you will be alerted to the precise moment that your clock is right. A few readers pointed out that you need only 720 broken clocks to set them so that whatever the time on of them gives it to the nearest minute. Nicholas James went further still, arranging his 720 broken clocks in a huge circle, so that the shadow of the sun tells you which one is correct.

CG Noel has the broken clock in his car set to 12 o'clock, so that it is always lunch time. He has also tried turning it back, in the hope that motorways will go away. John and Fiona Earle use broken clocks to calibrate stop-watches, stop lights and stop-go economies. Mollie Caird dismantles her broken clocks, using the hair springs in beauty salons to create curls and offering the mainsprings to Yorkshire Water in dry summers.

"Broken alarm clocks," says Jill Warner, "make excellent gifts for people who enjoy a lie-in." Pauline Fleming says they make idea gifts for people who like timeless presents. RJ Pickles bought his broken clock in a second- hand shop. Tony Toombs advocates using the spare hands to get rid of tics. The rest he sees as a headstone for a dead cuckoo.

Susan Tomes says that broken clocks would make ideal civil servants, "as they are guaranteed not to strike. They are also imperturbable, as you can't wind them up." George Tzilivakis says: "With a dozen broken clocks, you could place them in a line along your mantelpiece, and adjust the hands to spell "What's the time?" in semaphore. He also suggests that they could be a useful tick repellent in the summer.

Michael Hyde advises anyone with a broken clock to programme a music synthesizer to chime on the quarter-hours. Tony Bremner suggests hanging broken clocks in groups of six from wire coat-hangers, to be hung in doorways or windows to act as wind chimes in breezy weather. Robbie Jones says they may be used to convince someone you don't like that they are in fact dead. Marginally less cruelly, he recommends training unemployed youths to move the minute hand every 60 seconds on broken municipal clocks, thereby giving them valuable work experience.
