Yes 2016 will be a much longer year than usual. By one second. That is 31,536,001 seconds instead of 31,536,000. Be ready for a long night.

Happy New Year

And in case you are interested in building your own atomic clock here is a nice one, done the old fashioned way. It is mainly analog computing. But you do need a little board for the final decoding. I’m going to use this one. I’m going to upgrade it with the LPC1115. It has more memory. And I have just the software development system that can use it.
