All our computers, phones, tablets, GPS systems and whatever need to know the\u00a0<em>exact<\/em> time down to probably millionths of a second or else there can be problems. The majority of us wouldn&#8217;t notice anything serious yet the astronauts living on ISS, satellites in the GPS system and sadly, weapons do. I once heard on\u00a0<em>Stuff You Should Know<\/em> mention how those living on ISS pull ahead of us by a thousandth of a second every year and they&#8217;re only 400 km above the earth. Imagine how far ahead the hardware providing TV, the weather and other vital data get? Meanwhile, one of Phyllis Schlafly&#8217;s\u00a0dipshit offspring (Andrew) runs a moron\u00a0<em>conservative<\/em> wikipedia claiming relativity is a Liberal lie amongst other willfully ignore myths.

UTC was developed over the decades to get everything precise since we know the Earth isn&#8217;t consistent with its rotation nor our revolution around the Sun is changing microscopically as our star loses mass. The earthquake that caused the horrible tsunami in 2004 knocked the planet&#8217;s axis off by 0.1\u00b0! By the Fifties and Sixties, Scientists gained agreement on the Caesium-133 (we Yankees spell it Cesium) atom&#8217;s radiation periods or wavelengths; somebody who&#8217;s more knowledgable on this jump in please! Either way, this has been pretty solid but remember, Earth doesn&#8217;t always to follow the rules and on this day 50 years ago, the atomic clocks as they&#8217;re called, had to add a second to keep synchronization; ergo it wasn&#8217;t midnight July 1, 1972 until 23:59:60 of June 30, 1972 came and went. After then, we&#8217;ve had 26 more seconds added (all in my lifetime!) on either June 30 or December 31. I barely\u00a0remember the last two added in 2015 and 2016 respectively. Next year, the process is up for review to see if there&#8217;s a better plan.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We must be getting better at this because I haven&#8217;t seen warnings at work about this happening in a some years.
