An upcoming International Telecommunication Union (ITU) conference [theregister.co.uk] is about to become an international battleground over whether or not to retain the leap second – the periodic adjustment of Coordinated Universal Time (UTC) so it stays in agreement with atomic clocks.
The debate's expected to be so intense it will continue throughout the World Radiocommunication Conferences (WRC), which have an agenda spanning more than three weeks starting November 2.
In spite of frequent predictions of a leap second apocalypse, the last leap second passed pretty much without incident. Still, factions in the world of international standards keep the issue ticking over.
That wasn't the case in 2012, when Australian airlines Qantas and Virgin Australia both staggered when the Amadeus booking system crashed, and servers run by Mozilla, Reddit, Yelp, and FourSquare struggled. By contrast, 2015 was so unremarkable that some people argue we've worked out how to deal with leap seconds, so we may as well keep them.
