NIST's leap-seconds.list was finally updated today. Patch attached. I'd reached out to Christian Bizouard of IERS a bit ahead of the announcement in the hopes that we could settle the outstanding issues from 2017 with adding a public domain copyright notice to the IERS version of the file, but no luck this time around. -- Tim Parenti On Thu, 4 Jul 2019 at 12:11, Kurt Roeckx <kurt@roeckx.be> wrote:

Bulletin C 58
To authorities responsible for the measurement and distribution of time
INFORMATION ON UTC - TAI
NO leap second will be introduced at the end of December 2019. 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
Leap seconds can be introduced in UTC at the end of the months of December or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every six months, either to announce a time step in UTC, or to confirm that there will be no time step at the next possible date.
