Guidelines

• It is mandatory (MUST) to use the IANA Time Zone Database to represent string data formatted as time zones.

Overview of the IANA Time Zone Database

The IANA Time Zone Database, also known as the tz database or zoneinfo database, is the globally recognized standard for time zone information. It provides a comprehensive and detailed set of time zone rules and historical records, including:

1. Time Zone Names: Standardized time zone identifiers, such as America/New_York, Europe/London, and Asia/Tokyo.
2. Offset Information: Details of each time zone's offset from Coordinated Universal Time (UTC), including historical changes due to daylight saving time and other adjustments.
3. Conversion Rules: Rules for converting between standard time and daylight saving time, including start and end dates.

Example

An example of an IANA time zone identifier is:

America/New_York

This represents the time zone for New York, USA, including its standard time and daylight saving time rules.
