The first half of this year seemed longer than the same period a year ago. I could not quite put my finger on it. Then I read this!!
Midnight came later on Tuesday as for the first time in three years an extra second was added to the official time set by atomic clocks.
The "leap second" means the last minute of June had 61 seconds in it.
Leap seconds - and leap years - are added as basic ways to keep the clock in sync with the Earth and its seasons.
