If you were sitting on this rather lovely verandah at the stroke of midnight on December 29th. of this year, exactly how many whole seconds +/- would elapse before the New Year rings in?
A biannual event which could have occurred today, but didn't, may affect the answer.
From midnight on December 29 until the New Year rings in should be 172,800 seconds unless they throw in a leap second this year. The last one was December 31, 2008, and we did not get one today, so we are about due.
