Good to know

On December 31, 2016, at midnight we will have to deal with an unusual time ‐ the second 23:59:59 (UTC) is followed by 23:59:60. Afterwards January 1, 2017, starts with 00:00:00 (UTC). The reason for this phenomenon?! Another leap second is going to be inserted!

This declaration was announced by IERS (International Earth Rotation and Reference Systems Service) on July 6, 2016.

If you are running a hopf clock system, you do not have to worry about a thing ‐ the leap second will automatically be inserted!

In case you are wondering why leap seconds have to be inserted from time to time, here is a short explanation for you:

As day length increases because rotation of the earth globe continuously decreases, the UTC-time needs to be adapted to the actual rotation of the earth. This is done via the leap second!
