All I want for Christmas is a negative leap second

    *squints* I see what you did there Interesting article. I'm aware of leap seconds, there was a minor concern at my job that one of them in like....2014??? would cause outages bc of some legacy...

    The suggested alternate approach is to just let the gap between UTC and UT1 grow for 50 to 100 years until it's something on the order of 60 seconds, and then introduce an entire leap minute.

    It's going to be unrewarding and supremely unpopular and everybody's going to hate it at least sixty times as much as they hate leap seconds now.

    Interesting article. I'm aware of leap seconds, there was a minor concern at my job that one of them in like....2014??? would cause the apocalypse outages bc of some legacy systems but from what I recall, we actually managed with no outages or maybe one or two reboots. negative leap seconds though? horrible. awful. god I hope not, but I admire the author's desire for chaos lol

        lmao yup, sure was . Gotta love java! and by "love" I mean "loathe and thank the fates I'm on the server side of the house and don't have to deal with it too much"

        lmao yup, sure was is, really, we're still running it. Gotta love java! and by "love" I mean "loathe and thank the fates I'm on the server side of the house and don't have to deal with it too much"

    Oh lord, I hope not. If the mad lads at IERS actually do it, it will break so much shit. Honestly, we should just drop UT1 altogether. It doesn't solve any real problem. UTC already isn't coupled...

    Honestly, we should just drop UT1 altogether. It doesn't solve any real problem. UTC already isn't coupled to any useful property of the Earth's rotation across 23/24ths of its surface; Iceland can complain, I guess, but the worst credible outcome of abandoning the Earth's rotation as the world's largest pendulum clock is that, in a thousand years or so, some countries get to contemplate skipping a DST transition (because that abomination will definitely outlast human civilization) to put their local clock time in better sync with their local solar time.

    I don’t see any reason not to simply wait until the earth’s rotation starts slowing down again, which is certain to happen. It’s bound to be less harmful that trying to engineer a negative leap...

    I don’t see any reason not to simply wait until the earth’s rotation starts slowing down again, which is certain to happen. It’s bound to be less harmful that trying to engineer a negative leap second, when for all we know we’re just going to have to insert a positive one shortly thereafter.
