Daylight Savings Clock

Daylight Savings Clock
At first glance this looks like a normal clock that is missing a minute hand, but it has been designed to make it easy to adjust for daylight savings time. To set the clock an hour forwards you simply tilt it to the right and to set it back an hour you tilt it to the left, simple as that. It is a re-make of the design I found here

The clock has markings for hours, quarter hours and half hours so as you can see in the picture the time is about 8:25.

The reason the minute hand is omitted is because when the clock is adjusted as well as changing the hours by one hour it would also change the minutes by five minutes. I left the second hand on because although it will also be changed by 5 seconds when the clock is adjusted this is such an insignificant amount of time that it really makes little difference.

I'm writing this in the joyous knowledge that Daylight Suffering Time has finished.

This is a brilliant piece of ART.

I sums up the chaos of the transition to and from DST.

People often complain about the "extra hour of sunlight fading the curtains"--that may only be a joke, but you try getting kids into bed on a stinking hot night while there's still light outside.

This clock looks like it has suffered some of the worst effects of DST: it looks like it's melted, and the missing hand just completes the illusion.

I LOVE IT!

Had you though about doing this in a way that didn't chop off the markings?

that could be done by simply extending the marking further towards the center of the face.
