Access to raw data

type TZDescription = Either (ByteString, ByteString) (ByteString, TZLabel, ByteString)Source

Type of the elements of the compiled-in time zone info database.

Right is a primary location; fields: name, label, abridged content of the Time Zone info file

Left is a location which is an alias for a primary location; fields: name, name of the target

Abridged means that we only store the second part of the TZif file for version '2' and '3' files.

tzDescriptions :: [TZDescription]Source

The list with raw data of the compiled-in time zone info database.

The list is guaranteed to be in the order of TZLabel constructors (it is sorted by name).
