IEC 61850 UTC time stamp next leap second this month

Dear All,

The IEC 61850 time stamp uses the UTC time. The next leap second will be added on December 31, 2008:

2008 December 31, 23h 59m 59s
2008 December 31, 23h 59m 60s
2009 January 1, 0h 0m 0s

That means Dec 31, 2008 is one second longer than any other day in 2008!

As a consequence my birthday is (one second) longer than yours!! Yes, my birthday is Dec. 31 ...

I hope your SCADA and EMS systems take care of my birthday and adjust their glocks by inserting one "Karlheinz" second on Dec 31, 2008.
TAI, Temps Atomique International, is the international atomic time scale based on a continuous counting of the SI second. TAI is currently ahead of UTC by 33 seconds ... soon 34 seconds.
