Remember saying that you would like more time? Well, today, your wish will come true. It isn’t a whole lot, but it’s at least something.
Normally, 6:59:59pm is followed by 7:00:00pm. Today, in the east coast, 6:59:59pm will be followed by 6:59:60pm and then you’ll get to 7:00:00pm. If you are on the west coast of the USA, then this will all happen at 3:59:59pm
So today, you get some extra time and it is called a leap second. Don’t waste it all at once.
