I'm writing to inquire if I should prepare any of our MariaDB/Galera users for the upcoming leap second. According to http://www.timeanddate.com/time/leapseconds.html the next leap second will be added on June 30, 2015 at 23:59:60 UTC.

I searched a bit for "leap second mariadb" but didn't find anything recent.

Most of our users are on MariaDB 10.0.13 and Galera 25.2.9 or subsequent.

Have anyone tested both MariaDB and Galera to ensure that there are versions which are resilient to the introduction of a leap second? If so, is there documentation of versions which are known vulnerable to or proof against it?

Thanks!
