Understanding the Timezone Reference Tool

The Timezone Reference is a comprehensive database of IANA (Internet Assigned Numbers Authority) timezones. It's an essential resource for developers working with dates and times, allowing you to quickly look up official timezone names, their UTC offsets, and whether they observe Daylight Saving Time (DST).

Features

• Complete IANA Database: Contains a vast list of official timezone names used in programming languages and operating systems.
• Intelligent Search: Quickly find the timezone you need by searching for its name (e.g., Europe/London), a major city, or its UTC offset (e.g., GMT-5).
• Grouped by Region: Timezones are logically grouped by continent or region (e.g., America, Europe, Asia) in an accordion view for easy browsing.
• Clear Information: Each entry clearly displays:
  • The full IANA timezone name.
  • A common city or description.
  • The standard UTC offset.
  • A "DST" indicator if the region observes Daylight Saving Time.

How to Use

1. Browse: Simply scroll through the list. The timezones are organized by region. Click on any region name (e.g., "America") to expand the list of timezones within it.
2. Search: Use the search bar at the top right of the card. Start typing any part of the timezone you're looking for. The list will filter in real-time to show you matching results. For example:
   • Typing sydney will show Australia/Sydney.
   • Typing UTC+9 will show timezones with that offset, like Asia/Tokyo.
   • Typing pacific will show you all timezones in the Pacific region.
