It was an ordinary day. Reading about losing a second in time in 2029. Think you'll miss it. Well, it seems like earth's changing spin is threatening to toy with our sense of time, clocks and computerized society in an unprecedented way...but, only for a second. For the first time in history, world timekeepers may have to consider subtracting a second from our clocks in a few years because the planet is rotating a bit faster than it used to. Clocks may have to skip a second - called a "negative leap second" - around 2029, a study in the journal Nature said Wednesday. And, I say...so what! You know what that means? It means that I might miss a button on my keyboard and no one will know it. Maybe I'll say a word that my wife might not hear. But, it's said to be a BIG DEAL. It will make a change in the earth's rotation that's going to lead to some catastrophe event! Nah! You won't even know it when it happens! Story said that we are headed toward a negative leap second. The Earth takes about 24 hours to rotate, but the key word is about. For thousands of years, Earth has been generally slowing down, with a rate varying from time to time. The slowing is mostly caused by the effects of tides, which are caused by the pull of the moon. This didn't mater until atomic clocks were adopted as the official time standard more than 55 years ago. That established two versions of time - astronomical and atomic - and they didn't match. Astronmical time fell behind atomic time by 2.5 milliseconds every day. That meant the atomic clock would say it's midnight, and to Earth it was midnight a fraction of a second later. But...suppose you were asleep at the time! How awful will you feel it that happens? Then I found out that the earth's speeding up because its hot liquid core acts in unpredictable says, with eddies and flow that vary. Do you really care? For decades, astronomers had been keeping universal and astronomical time together with those leap seconds. Funny...but my science teacher in high school never told me that. Of course it could have been that pretty girl to my right that was keeping my attention. So, do we need to make an adjustment to handle that mini-second? In 2022, the world's timekeepers decided that starting in the 2030s they'd change the standards for inserting or deleting a leap second, making it much less likely. Tech companies unilaterally instituted their own solutions to the leap second issue by gradually adding fractions of a second over a full day. So, you will never know about that second! Then add in the "weird" effect of subtracting, not adding a leap second. It's likely to be tougher to skip a second because software programs are designed to add, not subtract time. Are you totally lost yet?? I am!! I say that we just blink twice on November 17 and everything will be OK. But...I just know that someone will make a big fuss about that. If they would just shut their mouth for an instant...it would all be over! Wouldn't that be much easier? It was another extraordinary day in the life of an ordinary day. PS - Did you see that I added an extra . in my last sentence so we are all OK with current time. But wait...I added yet another one...so now we are all screwed up again! Why can't life be easier than all this crap? It was another extraordinary day in the life of an ordinary guy.
