Time keeping


It used to be simple to keep time, just observe the length of the shadow of the stick as it follows the position of the sun as it crosses the sky. Not any more, my uncle sundial stick at the Alamarat village is not any more accurate as it is going to loose one more second by the end of this year 2008. Yes, due to earth rotation slowing down and the way Seconds are defined, the atomic clocks around the world will have to add one leap second this 31 December 2008 at 23:59:59 UTC time, effectively delaying the entry of a new day by one second. To imagine what could happen if no adjustments are introduced, in a loooooooooong run, the clocks will show the coming of a new weekend while it is still working day! since 1972, there have been 24 seconds added already to keep up with the earth draging.
When our ancestors used to watch the stars, it was enough for them to make out the different seasons to decide what to plant or harvest. With that in mind, it is good reason for us to keep watching the sky and admire the God creation without thinking and bothering ourselves with the complexity of time frames of Einstein.
