Introduction
The Time Zone API provides a simple interface to request the time zone for locations on the surface of the earth, as well as the time offset from UTC for each of those locations. You request the time zone information for a specific latitude/longitude pair and date. The API returns the name of that time zone, the time offset from UTC, and the daylight savings offset.
Before you begin
This document is intended for website and mobile developers who want to include time data on maps provided by one of the Google Maps Platform APIs. It provides an introduction to using the API and reference material on the available parameters.
Before you start developing with the Time Zone API, review the authentication requirements (you need an API key) and the API usage and billing information (you need to enable billing on your project).
