 * Generated from the official time zone database version 2018g. Canonical time zone names, aliases, UTC offsets, and daylight-saving time changes.
 * Minimal interface for time zone lookup and conversions. Parsing, formatting and manipulating dates is usually the task for a higher-level date library.
