structure Std.Time.Database.TZdb : Type

Represents a Time Zone Database (TZdb) configuration with paths to local and general timezone data.

• localPath : System.FilePath

  The path to the local timezone file. This is typically a symlink to a file within the timezone database that corresponds to the current local time zone.

• zonesPaths : Array System.FilePath

  All the possible paths to the directories containing all available time zone files. These files define various time zones and their rules.
