There are 61 seconds in a minute? Huh?

Ever just wish there was more time in the day? Well guess what, you got your wish!  Today at 23:59:60 UTC ( 7PM here in Missouri ) there will be an extra second added to the clock. No this isn't a joke, it's called a leap second, and it keeps our official time in sync with the earth's gradually slowing rotation. If it weren't for this extra second every few years a some hundred years down the road it would be daylight at 2 or 3 or in the morning, and we just can't have that!  So to keep nighttime dark and daytime light an extra second is added when it's determined nessesary. There is no set schedule for it,  but the last insertion was the same day in 2012. Since the system was created in 1972 there have been 25 leap seconds added to our time. This will therefore be number 26. What will you be doing at 6:59:61 PM tonight?
