What country or multinational group is in charge of keeping the world clock wound up and on time?
"NIST-F1 is a caesium fountain atomic clock that serves as the United States’ primary time and frequency standard. As of the summer of 2005, it is so accurate that it will neither gain nor lose one second in more than 80 million years. The clock took less than four years to test and build, and was developed by Steve Jefferts and Dawn Meekhof of the National Institute of Standards and Technology (NIST) physics lab in Boulder, Colorado."
