Leap Second Coming In June, 2012

[Daniel]

IERS have just announced a leap second due at midnight, June 30th this year. Are your systems ready?

The last leap second added was at the end of 2008

systems?

the 'second coming' part on this thread's title got me here

A leap second is a positive or negative one-second adjustment to the Coordinated Universal Time (UTC) time scale that keeps it close to mean solar time. UTC, which is used as the basis for official time-of-day radio broadcasts for civil time, is maintained using extremely precise atomic clocks. To keep the UTC time scale close to mean solar time, UTC is occasionally corrected by an intercalary adjustment, or "leap", of one second. Over long time periods, leap seconds must be added at an ever increasing rate (see ΔT). The timing of leap seconds is now determined by the International Earth Rotation and Reference Systems Service (IERS). Leap seconds were determined by the Bureau International de l'Heure (BIH) prior to January 1, 1988, when the IERS assumed that responsibility.
When a positive leap second is added at 23:59:60 UTC, it delays the start of the following UTC day (at 00:00:00 UTC) by one second, effectively delaying the UTC clock. Negative leap seconds have never been needed. For one to be needed within a year the length of day (LOD) would have to decrease by 1⁄365 second, or about three milliseconds. While LOD does fluctuate, it is currently much as it was in 1820, and historic eclipse observations show that LOD tends to increase by roughly two milliseconds per century. A decrease of 4 milliseconds did occur around 1920, but that required more than a decade of continuous acceleration.

I use NTP on my systems!
They fix the timers, I got mine fixed. Automagically!

Leap seconds are a tiny bit of problem when you have to time-stamp transactions coming in from all over the globe and keep them in date/time order. Some OSes don't support leap seconds, which complicates matters.

A really really big earthquake can fix this 1 second problem
