Leap Seconds: Keeping our clocks in time with the sun

The UK Public Dialogue

Take the Questionnaire Join the Discussion

How important is this to you? Have your say.

In 2015, the international community will come together to make a historic decision on whether to keep time linked to the sun and the earth's rotation or to stop adding the leap seconds which maintain the link. Some people would like time in the future to be based solely on highly accurate atomic clocks. This would minimise some problems with computers because leap seconds would no longer have to be added to keep atomic time in line with solar time. Others argue that stopping leap seconds would cause other technical problems now and in the future, as well as breaking our cultural relationship between the sun and the time on our clocks.

The UK government is holding a dialogue to understand how the public feels about the connection between the sun and time. We are interested in hearing your views.
