tz database

The tz database, also known as the IANA Time Zone Database, is a collection of data that records the world's time zones, daylight saving time rules, and how they change over time. It helps computers and software accurately convert times across different locations by providing standardized information about local time standards. Maintained collaboratively, it accounts for historical changes and regional variations, ensuring that time-related data remains consistent and reliable globally. Essentially, it acts as a comprehensive reference for understanding and managing local times worldwide.
