The following submission statement was provided by /u/yourSAS:
The decision was made by representatives from governments worldwide at the General Conference on Weights and Measures (CGPM) outside Paris on 18 November. It means that from 2035, or possibly earlier, astronomical time (known as UT1) will be allowed to diverge by more than one second from coordinated universal time (UTC), which is based on the steady tick of atomic clocks. Since 1972, whenever the two time systems have drifted apart by more than 0.9 seconds, a leap second has been added.
Leap seconds aren’t predictable, because they depend on to Earth’s natural rotation. They disrupt systems based on precise timekeeping,
Future metrologists might find more elegant ways than the leap second to realign UTC and UT1.

So what's going to happen when clocks diverge going forward? Will that create issues with precision or solve them? I genuinely don't understand this problem.
Jeez, more tyranny from the members of Big Clock. Where will it end???
So daylight savings time is also universally banned this day?

Or else, yolo!
Clocks aren’t diverging, the earth’s rotation changes when big earthquakes happen.
The issue would be the clock will not match the point of the sun in the sky… by a second or two.
Big Clock has a monopoly on timekeeping
Mid life? More like end of life.
I'm in my 50s and I took COBOL in college in the 80s, but never used it in my entire coding career over the last 35 years. I know it's still out there, but even when I took the class the guys actually doing it were the age I am now.
GCWM votes to just hold a leap "10 minutes" at some point in the future.
Wow so my sun dial about to be phased out??
Then, how does this clock work and keep perfect time?
Super interesting, thanks for sharing!
All programmers that have to maintain anything dealing with timestamps, really.
This looks like a job for FREE MARKET ECONOMICS MAN!

Nobody told me about this vote the rest of the world took, geez.
This doesn't say a word about leap seconds. Even the most accurate mechanical clocks will drift for multiple seconds per year, so even if it was possible to know them in advance, it wouldn't make much sense.
I'll be looking forward to the trickle down economics...
Because it’s not predictable. It’s in the article.
That’s the minority.
No wonder I didn't see you there that day
not just earthquakes. inner earth isn't perfectly balanced, which can throw off rotation. the moon creates drag. oceans... etc, etc.
my timeframe might be off but back when dinosaurs were around, days were 22h. rotation has been slowing for a long time.
Pangea must have been hell for UTI.
Sun doesn’t match the clock pretty much everywhere. That’s a good enough reason not to bother with leap seconds. If the difference doesn’t balance out naturally then they can have a leap 22 seconds when it’s needed.
Cue the sun
Ok, I’ll bite. Please explain the proper length of day and how it addresses the discrepancy between atomic and astronomical times.
