Did I mention?

I meant to let you know there would be no leap second at the end of June but I forgot. You probably didn't miss it.

While I'm at it, there won't be a leap second on December 31st either so you'll not get an extra kiss on New Year's Eve.

In the meantime the difference between Coordinated Universal Time UTC and the International Atomic Time TAI is:

 from 2017 January 1, 0h UTC, until further notice : UTC-TAI = -37 s

You can get more information from the Earth Orientation Center.
