This repository contains two C libraries:

• TimeZoneDatabaseCreator: This library extracts time zone data from the IANA time zone database and generates C code files for use in embedded systems.
• TimeZoneOffsetCalculator: This library calculates time zone offsets based on the generated data.

• Microsoft Visual Studio 2022 (Version 17.12.0 or later) is recommended for building the TimeZoneDatabaseCreator.
• A C compiler for the target platform of your embedded system.

1. Download the latest Data Only Distribution from https://www.iana.org/time-zones.
2. Extract the downloaded archive to a suitable location.

1. Open the TimeZoneDatabaseCreator solution in Visual Studio.
2. Configure the project to point to the extracted IANA time zone database.
3. Build the solution.

1. Include the generated C code files and the TimeZoneOffsetCalculator library in your project.
2. Link your project with the TimeZoneOffsetCalculator library.
3. Use the provided functions to calculate time zone offsets based on a given date and time.
