So a vote will be taken in October to put a stop to further leap-second adjustments; if this goes ahead, UTC (the atomic-clock time reference) and UT1 (referenced to the Earth’s rotation) will be allowed to diverge beyond their current maximum difference of 0.9 seconds in future, until the discrepancy is (according to the article) as much as one hour.
What happens after that? Presumably somebody will come up with a bright idea for what to do next, in the centuries between now and then ...
We will probably have a leap hour instead of a leap minute as currently practised. Cheers Michael.
