A leap second will be added to time next week but watch out - chaos may ensue

July will be late this year, because the last minute of June will have 61 seconds. In the unlikely event that you are awake as midnight (GMT) approaches next Tuesday, and looking closely at an atomic clock, you might even notice it. While 23:59 and 59 seconds normally turns to 00:00:00 – midnight – a strange additional second will make the time 23:59:60.
