To adjust for the difference between the very precise time measured by atomic clocks and the actual position of the earth around the sun, the 31st of December 2005 will be one second longer. Kinda weird. Last time this happenned was in 1999. Overall, 22 seconds have been added since the creation of this system in 1972. Question to think about for the reader: is your life now longer or shorter due to the addition of a second to 2005?
