The last time a leap second was added, it caused issues with a number of servers running Linux due to a livelock. [0] This had an effect on EC2 [1] and apparently other pieces of software [2] as well.
Nice to see Amazon being proactive about the forthcoming change. Time is just a prime example of one of those things that seems superficially simple, but turns out to be deviously complicated. (If you ever want to bore non-technical types to death at a party, just start talking about the history of time. Bonus points for mentioning the proleptic Gregorian calendar in context.)

- cperciva 11y agoThis had an effect on EC2 I don't think the leap second bug had any effect on EC2 itself; the only reason EC2 was ever blamed is that many of the sites which had issues happened to be hosted on EC2.
- stygiansonic 11y agoCorrect, my bad. Thanks for catching the mistake.
