A decision on whether to abolish the leap second - the occasional, extra second added to the world's time - has been deferred.
Experts at the International Telecommunication Union (ITU) were unable to reach a consensus, so moved the matter to a meeting in 2015.
The US argued at the meeting that leap seconds were causing problems for communication and navigation systems.
But the UK said that the long-term consequences of losing it were great.
