A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time.
The UTC time standard, which is widely used for international timekeeping and as the reference for civil time in most countries, uses the international system (SI) definition of the second, based on atomic clocks. Like most time standards, UTC defines a grouping of seconds into minutes, hours, days, months, and years. However, the duration of one mean solar day is a slightly longer than 24 hours (86400 SI seconds). Therefore, if the UTC day were defined as precisely 86400 SI seconds, the UTC time-of-day would slowly drift apart from that of solar-based standards, such as Greenwich Mean Time (GMT) and its successor UT1. The purpose of a leap seconds is to compensate for this drift, by scheduling days with 86401 or 86399 SI seconds.
Because the Earth's rotation speed varies in response to climatic and geological events, UTC leap seconds are irregularly spaced and unpredictable. Insertion of each UTC leap second is usually decided about six months in advance by the International Earth Rotation and Reference Systems Service (IERS), when needed to ensure that the difference between the UTC and UT1 readings will never exceed 0.9 second. Between their adoption in 1972 and June 2012, 25 leap seconds have been scheduled, all positive.

PARIS, FRANCE — The world is preparing to add a leap second at the end of June to synchronize the world's clocks with the Earth's rotation. The leap second was scheduled by the Paris Observatory to compensate for the slowing of the Earth's rotation on June 30, when clock dials will read 23:59:60 to synchronize atomic time with the Earth's rotation. The leap second was first introduced in 1972 and it has been used 25 times since then. The most recent leap second was added in 2012, when several websites including including Reddit, Yelp and Linkedin reported crashes and problems with the Linux operating system and programs written in Java. -

If you know about upcoming leap second on June 30, 2015, you know that a time discontinuity can cause problems with distributed computing processes. While network time protocol tells that an extra second is coming, it is up to the OS and the application to manage it in such a way that it will not disrupt the operation.

Leap second: June will be one second longer this year, problems with Linux, Java expected - TomoNews
- Order: Reorder
- Duration: 1:16
- Updated: 04 Jun 2015
PARIS, FRANCE — The world is preparing to add a leap second at the end of June to synchronize the world's clocks with the Earth's rotation. The leap second was scheduled by the Paris Observatory to compensate for the slowing of the Earth's rotation on June 30, when clock dials will read 23:59:60 to synchronize atomic time with the Earth's rotation.
The leap second was first introduced in 1972 and it has been used 25 times since then. The most recent leap second was added in 2012, when several websites including including Reddit, Yelp and Linkedin reported crashes and problems with the Linux operating system and programs written in Java.
There are fears that similar Internet problems could reoccur on June 30, and markets, especially in Australia, are wary of possible mishaps when the leap second is added.
Google has developed a special method to handle the leap second. It gradually adds milliseconds to its system clocks during a 20-hour smear window prior to the arrive of the leap second.
"At the end of the smear window, the entire leap second has been added, and we are back in sync with civil time," the company said in a blog post.
Web businesses have been the main opponents of the leap second, which scientists say is essential for research purposes. Members of the International Telecommunications Union will meet later this year to determine whether to scrap the leap second permanently. If so, experts say atomic time could slip up to three minutes ahead of the Earth's rotation by 2100, and about 30 minutes by 2700.
