President Obama is urging Americans to "make that extra second count."
"This is a unique opportunity for America to use the leap second to make the world a better place," the president said.
"Use that time to call a gay friend and urge him to marry. Teach an undocumented immigrant how to read a book or a voting machine. Flick the switch to turn off coal-burning generators and other devices. Take down that Confederate flag--it only takes a second."
The president will take his "Make Leap Second Count" campaign to Seattle and Portland today.
