The tz database, also called tzdata, the zoneinfo database or IANA (Internet 

Assigned Numbers Authority) time zone database, is a collaborative compilation 

of information about the world's time zones, primarily intended for use with 

computer programs and operating systems. It is sometimes called the Olson 

database, referring to the founding contributor, Arthur David Olson. Paul Eggert 

is currently its editor and maintainer.



AmigaOS now has its own version with full support for all time zones. So far 

only Classic Amiga OS is supported but support for at least AROS is planned. 

AmigaOS 4 might already have support for this database. I haven't been able to 

find any information about it online. Read more about the database at Wikipedia 

or IANA. The primary usage is to keep your Amiga clock synced regardless of 

changes in summer and winter time. Other application might also benefit from the 

database, f.x. network time synchronization software. The software also include 

small tools, one of them being able to show the time in other parts of the 

world.



The Amiga Time Zone Database is steadily hardening. Hopefully version 5 can be 

promoted to stable. All code and data are open sourced. To get the most out of 

The Time Zone Database a RTC module is required. Are you a developer or maybe 

just a curious Amiga user, then you can download The Amiga Time Zone Database 

from aminet.
