I don't really understand why leap seconds aren't "needed" a lot more often then they are. According to Wikipedia, a modern day is 1.7 milliseconds longer than a day a century ago. Assuming the second was standardized 200 years ago so it's over 3 milliseconds a day, shouldn't we need a leap second every year or so?
- funac 3y agothe discrepancy between solar & atomic time is noisy & irregular; the past several decades have introduced comparatively less deviation & have required fewer leap seconds as a result see: https://en.wikipedia.org/wiki/File%3ADeviation_of_day_length_from_SI_day.svg https://en.wikipedia.org/wiki/File%3ADeviation_of_day_length...
- lifthrasiir 3y agoYour instinct is indeed correct. Leap seconds aren't not frequent today because they only started 50 years ago, and you should see much more leap seconds in average for next 50 years. It also means that leap seconds are not sustainable in the long term for reasons other than computer glitches anyway.
