'Leap Second' Bug Wreaks Havoc Across Web

Posted July 01, 2012 1:21 PM

From Wired Top Stories:

Reddit, Mozilla, and several other big name web outfits experienced brief technical problems on Saturday evening, when software unpinning their online operations choked on the "leap second" that was added to the world's atomic clocks.

<..."Reddit did not immediately respond to a request for comment."...>

Was there a 1-second delay, then?

I guess Reddit had some 6 months delay, because that is how long in advance the leap second at 30 June '12 was announced.

I understand that Google implemented a smart ""leap smear", where it gradually adds milliseconds to its system clocks prior to the official arrive of the leap second." Way to go - or must the leap second be replaced by a leap minute or leap hour, which will happen less frequently?
