geolocation-to-timezone

This project aims to explore solutions for retrieving the timezone from geolocation using Java.

Solutions

We have identified two suitable offline solutions and a Google API for obtaining timezone information based on geolocation

• Timzeshape (Java Library, https://github.com/RomanIakovlev/timeshape)
• TimeZoneMapper (Java Class, https://github.com/drtimcooper/LatLongToTimezone)
• Google Timezone API
