All the time zone information used by the project is provided by tz database project. This database is used in quite a few systems out there including BSDs, GNU LibC, Java, Oracle, MacOS, Linux and etc.

TZDB is made of three modules:

  • TZUpdate, a small command line utility that takes as input the path to the tz rule files and generates a pascal source file filled with pre-packed constants.
  • TZDB, a package that contain only one unit: TimeZones. This unit implements a new class, TBundledTimeZone, derived from TTimeZone. This package is basically all you need.
  • TZVisualizer, a small VCL project that extracts time zone information from a given time zone. It writes all time intervals in a given year, their offset and etc.
