  • Our database is updated as soon as we verify the change so you can rest assured of accurate time within your application.

What You Get

  • Complete database in your choice of XML or ASCII comma delimited formats for easy import or direct use in any custom project development you create. (click for more info on the XML file or the ASCII file)

  • Email announcements when new versions of the databases are available.

  • Bonus for .NET Programmers: A .NET .dll you can use with our database to help you retrieve data or perform time calculations without the extra work of programming it yourself. This .dll is available for the .NET Framwork and .NET Core 3.1 and is the same one we use for our WorldTimeServer web site.

  • Optional: Map Polygons: For each of the time zone locations in our database, we now have Map Polygons in KML format available. (click here to download a sample) Polygons can be a valuable addition because they allow you to use Longitude/Latitude to pinpoint the matching time location.
