Unbelievable accuracy from a walmart watch
No shootski. The best example of value I have is a cheapy plastic LCD
watch I got at 7-11 some 20-25 years ago. $5.00. It kept PERFECT time for 10+ years until the battery died. Astounding accuracy, to a few seconds per year.

About 2 weeks ago, I set this watch very accurately to time that is kept by syncronizing with an NTP server (atomic clock), to the second. Today I checked time again whiel trying to be very good at catching the right moment. I typed "date" and pressed ENTER just as the arm of the watch passed :00:00. The result is that the watch is not even by one second off!!! Obviously, there are limits to my own precision in how I pressed the return key right when the watch ticked :00, plus the OS delay in starting "date", but in any case I could not detect any difference. I find it rather amazing, really. The watch is a quartz watch with hands, "water resistant". i -- -------------------------------------------------------------- Home Page: http://www.seanet.com/~jasonrnorth If you're not the lead dog, the view never changes Doubt yourself, and the real world will eat you alive The world doesn't revolve around you, it revolves around me No skeletons in the closet; just decomposing corpses -------------------------------------------------------------- Dependence is Vulnerability: -------------------------------------------------------------- "Open the Pod Bay Doors please, Hal" "I'm sorry, Dave, I'm afraid I can't do that.." |
