# A literary appreciation of the Olson/Zoneinfo/tz database - Host: [blog.jonudell.net](https://links.thingelstad.xyz/hosts/blog.jonudell.net/) - Saved: March 7, 2011 (2011-03-07T11:56:07Z) - Record: https://links.thingelstad.xyz/links/aed3e2dfa190/ - JSON: https://links.thingelstad.xyz/links/aed3e2dfa190.json ## From the page (probably an excerpt, not Jamie's words) You will probably never need to know about the Olson database, also known as the Zoneinfo or tz database. And were it not for my elmcity project I never would have looked into it. I knew roughly that this bedrock database is a compendium of definitions of the world’s timezones, plus rules for daylight savings transitions (DST), used by many operating systems and programming languages. ## Facts - Kind: [Page](https://links.thingelstad.xyz/kinds/page/) ## Same host - [Calendar cross-publishing concepts « Jon Udell](https://links.thingelstad.xyz/links/50976f5db3cb/) (blog.jonudell.net, March 10, 2007) - [Critical mass in the Goldilocks zone – Jon Udell](https://links.thingelstad.xyz/links/79cdcd02e194/) (blog.jonudell.net, January 1, 2024) - [Introducing XMLUI – Jon Udell](https://links.thingelstad.xyz/links/54fd9765fdc0/) (blog.jonudell.net, July 21, 2025) ## Saved the same week - [TileMill](https://links.thingelstad.xyz/links/2e68c244012a/) (tilemill.com, March 7, 2011) - [DanielRapp/Noisy - GitHub](https://links.thingelstad.xyz/links/de1b4b7cc8ad/) (github.com, March 7, 2011) - [Anatomy of a Crushing](https://links.thingelstad.xyz/links/75ad73084aa8/) (blog.pinboard.in, March 8, 2011) - [OmniFocus & GTD - Things I Like](https://links.thingelstad.xyz/links/6d488223f199/) (andrewminer.tumblr.com, March 8, 2011) - [S5: A Simple Standards-Based Slide Show System](https://links.thingelstad.xyz/links/79ab6c018852/) (meyerweb.com, March 8, 2011) ## Elsewhere - Wayback Machine: https://web.archive.org/web/*/http://blog.jonudell.net/2009/10/23/a-literary-appreciation-of-the-olsonzoneinfotz-database/
