In case you missed it, here is the leap second moment. I loaded several web and desktop clock displays. Notice how many of them didn’t take account of the extra second – but some did! For more details on what this means, see the post ‘Hang on a second‘.

Owing to an incredibly small discrepancy between the atomic clock length of a year and the time it takes for the sun to orbit the earth, and the dogged insistence of scientists for being as close as possible to correct all the time, tomorrow is the most recent in a series of days where time goes a bit weird momentarily due to the addition of a leap second. This means 30th June 2012 will last for 86,401 seconds instead of the usual 86,400. Internet mathematician and pedant Matt Parker reports this as an 0.00116% increase on the usual number of seconds in a day.
