tzdata package

leap-seconds.list file expires 28 June 2017

Asked by Ryan Kingsbury

The currently published tzdata package for supported distributions contains a leap-seconds.list file that expires on 28 June 2017 and that was based on data available up through IERS Bulletin C52.

IERS Bulletin C53 was published on Jan 9 2017 confirming that a June 30 2017 would not be issued. I'm not sure what serves as the upstream data source for this package, but both IEFT and the eggertz tz repo have a leap-seconds.list file that incorporates Bulletin C53.

https://www.ietf.org/timezones/data/leap-seconds.list
https://github.com/eggert/tz/blob/master/leap-seconds.list

Would it be possible to get the package updated to include these more recent files? Some applications make use of the expiration data in this file and will raise exceptions to the user if it has gone stale.

Digging into the source files I see that this change is already available in version 2017a and 2017b of tzdata but not in 2016j.
https://launchpad.net/ubuntu/+source/tzdata show the available versions for the different supported Ubuntu releases, and the upgrade to a 2017* version has not yet been done for the Ubuntu releases up to Yakkety.

I assume that the bug report Bug #1696298 that you have already created will trigger the backport of 2017b to the older Ubuntu releases.

Can you help with this problem?
