Practically all electronic digital clocks are 24-hour. The only problem is that an idiot light goes on for AM pr PM instead of the more logical solution of having a 24-hour display. About a year ago, I (after arriving late for work because I accidentally set my alarm for 6:30 PM instead of AM for what seemed like the 32767th time) took my digital clock apart, clipped one end of an alligator lead to the positive lead of the clock's power supply, clipped a 1K resistor to the other end, and started probing the unused terminals of the digital clock chip. Viola! The third one I tried, the display changed from 5:36 to 17:36. I soldered the 1K resistor in place and put the clock back together. One minor problem is that while virtually all clock chips support 24-hour displays, many clock displays only have 3 1/2 display digits. Therefore, 22:30 looks like (small superscripted 1) 2:30. I still prefer this to the AM/PM idiocy that I had before (and I haven't accidentally set my alarm for 6:30 PM since). -- David Barts Pacer Corporation davidb@pacer.uucp ...!fluke!pacer!davidb
