Hi all, please note the NIST leap-second file at ftp://time.nist.gov/pub/ has not yet been updated according to IERS bulletin C 51. It's still the version which has been published in July 2015, and will expire in June 2016. I saw that also tzdata2016a.tar.gz which has been published 2016-01-26 still contains the old leap second file even though bulletin C 51 has already been published 2016-01-11. I've dropped Judah Levine a similar note, but eventually you can include the IERS version of the file into the TZ DB distribution. The IERS file has already been updated and expires 2016-12-28.
