Wow...is this the same thing as the poles flipping?

[Choban]

Days are supposed to get longer this time of year, who do I write to get this time back? It adds up over a year and I want it back.
All joking aside, between the Hati Quake, the one in Chile and Japan last week, I'm sure there are bigger worries than microseconds on the world clock.

Crap, I already lack enough time and now this??

The axis' tilt is so bad now, as I'm writing this reply me and my computer table are sliding out the balcony door....

see it shortened time so much we're actually going .sdrawkcab

It shortened the day by about 1.26 microseconds. So, every 9.19 days, we loose one second.

They will need to adjust the GPS satellites ! Without the ajustment due to relativity in the GPS (yes, Einstein), the positioning would be off 10km/day and it's only 7 microseconds/day difference.

Wouldn't that be shorter by 1 second every 793650.793 days?

The axis has also supposed to have shifted 3".

1/1.26 microseconds gives 793650.793 seconds^-1
That means that every 793650.793 seconds, we get 1. Since the unit is a "second", we get a second every 793650.793 seconds which is 9.19 days (793650.793 / 3600 (hours) / 24 )

But if it's 1.26 microseconds per day, then it would it not take ~793650 days to accumulate one second, or 1,000,000/1.26?

Here's a day shortener for ya..

the "per day" statement is only a reference.

See it like this:

Every (3600 * 24 = 86400) 86400 seconds, 1.26 microseconds is lost.
That means that:
0.000 001 26 is lost every 86 400 seconds.

Multiply those two numbers, you get 0,108864 days^-1
Make that 1/0,108864, it gives 9,185773075 days.
