I'm installing the timezone tables on MySQL, which are generated from /usr/share/zoneinfo on my Debian Server. But there is a point on the notes about ensuring I keep them up to date whenever the zoneinfo files are updated. I've searched Google, but can't find the answer to the question: How often is `/usr/share/zoneinfo` updated? Is it every time that the Linux OS is updated, or is it infrequently?
How often is `/usr/share/zoneinfo` updated?
debian;timezone
The timezone data is updated every month or thereabouts. So far this year there have been seven releases from the IANA, which have all been made available as stable updates in Debian. There were seven releases altogether in 2015, ten in 2014, nine in 2013...If you want to set something up so that the MySQL timezone tables are updated whenever the timezone info is updated, you could look at adding a trigger against the tzdata package; that way, whenever tzdata is updated, the timezone tables will be updated too.
