Bugün öğrendim ki: Bilgisayarların ve işletim sistemlerinin yerel ayarları yapılandırmak için kullandığı zaman dilimleri veritabanını korumaktan sorumlu bir adam var. Adı Paul Eggert. Ve California'da yaşayan bir bilgisayar bilimcisi.
Collaborative compilation of information about the world's time zones [!(//upload.wikimedia.org/wikipedia/commons/thumb/c/cb/2017a.png/400px-2017a.png)](/wiki/File:2017a .png) The tz database partitions the world into regions where local clocks have, since 1970, all been the same. This map, made by combining the 2017a edition of the database with [OpenStreetMap](/wiki/OpenStreetMap "OpenStreetMap") data, is of all the regions outside Antarctica.  The **tz database** is a collaborative compilation of information about the world's [time zones](/wiki/Time_zone "Time zone"), primarily intended for use with computer programs and operating systems. Paul Eggert is its current editor and maintainer, with the organizational backing of [ICANN](/wiki/ICANN "ICANN"). The tz database is also known as **tzdata** , the **zoneinfo database** or **IANA time zone database** , and occasionally as the **Olson database** , referring to the founding contributor, Arthur David Olson . Its uniform naming convention for time zones, such as _America/New_York_ and _Europe/Paris_ , was designed by Paul Eggert. The database attempts to record historical time zones and all civil changes since 1970, the [Unix time](/wiki/Unix_time "Unix time") epoch. It also includes transitions such as [daylight saving time](/wiki/Daylight_saving_time "Daylight saving time"), and also records [leap seconds](/wiki/Leap_second "Leap second"). The database, as well as some reference [source code](/wiki/Source_code "Source code"), is in the [public domain](/wiki/Public_domain "Public domain"). New editions of the database and code are published as changes warrant, usually several times per year.
