Storage Engine Idea, tzdata - Mark Atwood

Storage Engine Idea, tzdata
I recently ranted that Sun JRE installs /usr/java/jre*/lib/zi/, a nearly complete timezone database in it's own java-ish format, instead of using the Olson database in ZIC format in /usr/share/zoneinfo/.

It turns out that MySQL does the same thing, it installs a set of MyISAM tables with the TZ database.

It won't be too hard to write a read-only storage engine that reads the /usr/share/zoneinfo/ ZIC files, and presents tables that "look" just like the currently used tz tables, basically doing what mysql_tzinfo_to_sql does, only "live".

MySQL doesn't actually use the tables unless you specify, and you can specify other data sources, iirc. Or rather, you can specify MySQL to use the tz tables, *or* you can say "use the system defaults".
