Hi, Java had some issues with 100% CPU usage when NTP was running during the additional second in 2012. http://blog.wpkg.org/2012/07/01/java-leap-second-bug-30-june-1-july-2012-fix/ Google did something different to get the extra second in: http://googleblog.blogspot.de/2011/09/time-technology-and-leaping-seconds.html Most devices probably don't even know about the leap second coming as that would require a firmware upgrade.

In UNIX, for instance, time is measured as the number of seconds since the UNIX epoch. imo, the counting of the number of seconds should not be "adjusted", unless there's a time warp of some sort. The leap second adjustment should be in the display of the time, i.e., similar to how time zones are handled. fwiw
