Dear users of tzdb,

IERS has announced a new leap second at the end of year 2016, see

https://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat

Another point:

I have myself written a time library in Java called Time4J which 
contains a tz compiler based on your data and which also evaluates the 
leap second file contained in tz-data. Hence this library could be 
listed in the file "tz-link" within the section "Other tz compilers" 
maybe with this description:

<a href="https://github.com/MenoData/Time4J/">Time4J &ndash; Advanced 
date, time and interval library for Java</a> , uses the class

<code>net.time4j.tool.TimezoneRepositoryCompiler.java</code> located in 
TZTool-module that compiles

<code><abbr>tz</abbr></code> source into a Time4J-specific binary 
format.  Time4J is available under a LGPLv2.1-licence.


Cheers and thanks for your very useful work

Meno

Hi Paul,

Is there any estimation when the new tzdata package containing the leap secon=
d information will be available?
We need to include it in our SW in the upcoming weeks.

Br,
Tibor

from us. (We don't copy the IERS files due to unresolved copyright issues.)

Thanks for the pointer. I modifed your suggested description somewhat
and installed the attached patch into the experimental version on
GitHub; please let us know if it has any problems.

October for later this year, and the leap-second change won't happen until af=
