A brief history of Leap Seconds

by John

A few weeks ago I gave a talk about Leap Seconds at Electromagnetic Field (EMF) – an extraordinary camping festival for hackers and makers, held in the UK every two years. I’ll be speaking a bit more about my time at EMF in an upcoming Worthing Digital talk: What we did at camp.
