This day will be one second longer than the day before or the day after.
Today is the 2015 Leap Second Day. From the UK Telegraph:
Clocks to read 11:59:60 tonight as time lords add leap second
Airlines, trading floors and technology companies are braced for chaos today as world timekeepers prepare to add a leap second to global clocks.
Immediately before midnight dials will read 11:59:60 as clocks hold their breath for a second to allow the Earth’s rotation to catch up with atomic time.
When the last leap second was added in 2012 Mozilla, Reddit, Foursquare, Yelp, LinkedIn, and StumbleUpon all reported crashes and there were problems with the Linux operating system and programmes written in Java.
In Australia, more than 400 flights were grounded as the Qantas check-in system crashed.
Experts at Britain’s National Physical Laboratory (NPL) who will officially add the second to UK time, warned that markets which are already jittery from Greece could suffer transaction delays if their software was not prepared.
“There are consequences of tinkering with time,” said Peter Whibberley, Senior Research Scientist in the Time and Frequency group at NPL, who is known to colleagues as ‘The Time Lord.’
“Because leap seconds are only introduced sporadically it is difficult to implement them in computers and mistakes can cause systems to fail temporarily.
99.999% of civilization will be unaffected. Cool idea though. The title of this post? The good Doctor of course.
