WASHINGTON — Tonight will STRETCH longer by a second. A leap second.

International timekeepers are adding a second to the clock at midnight universal time Saturday, June 30, going into July 1. That’s 8 p.m. EDT Saturday. Universal time will be 11:59:59 and then the unusual reading of 11:59:60 before it hits midnight.
Breaking news, Earth jumps tonight.

Question: Should I leave my PC off just before this happens?Isn't the "longest night" the Winter Solstice? (Dec 21/22 in the northern hemispshere, June 21/22 in the southern)

But when it is long in the north, it is short in the south.
Tonight is long north and south!
Should I have SAID it this way?
The longest 24 hour day this year

What about those who live either side of the international date line? For them did it already HAPPEN? Or is it STILL coming?Quote from: Geek-9pm on June 30, 2012, 12:32:31 PM

Tonight is long north and south!

That is a very GOOD point, which I missed.
