So researchers added ten seconds all at once in 1972 to the world's astronomical clocks, [Johnston,]explains. Inaccurately. Actually, UTC was set approximately equal to UT2 (a smoothed version of UT1) in 1958, and continuous adjustments had been made to civil time to keep it close to UT1 (time determined by earth's rotation) all along. Leaps, or discontinuities in civil time were made in multiples of 50 nanoseconds and the rate of UTC was slowed down by multiples of 15 parts per billion, to keep step with UT1. In 1972, the decision was made to bite the bullet, and allow UTC to "beat" atomic seconds, adding or removing a leap second as needed to stay with 0.9 seconds of UT1.

The 2012 leap second brought down Reddit, Gawker Media, and Mozilla. I won't cry if it does it again. Maybe this time Gawker will stay down.

So do we set our clocks backward or forward? /snort

Not one mention of Global Warming in any of that. I can’t believe it.

Can’t we just speed the earth up by a second?

Good afternoon. I hope you are doing well.
Fwiw, I am not participating in this manipulation of time. I will remain one second behind.
