TimeZone API Documentation

Github project

public TimeZone getTimeZone(Pair<String,String> latLng){
        //Find timezone from TimeZoneAPI
        GeoApiContext context = new GeoApiContext.Builder()
                .apiKey("API KEY")
                .build();
        LatLng location = new LatLng(Double.valueOf(latLng.getLeft()), Double.valueOf(latLng.getRight()));
        TimeZone tz = null;
        try {
            tz = TimeZoneApi.getTimeZone(context, location).await();
        } catch (ApiException | InterruptedException | IOException e) {
            e.printStackTrace();
        }
        return tz;
    }

From the invoking method, the response can be collected with java.util.TimeZone

//Time Zone from Google
TimeZone timeZone = getTimeZone(Pair.of(latitude, longitude));
System.out.prinln(timeZone.getID());
System.out.prinln(timeZone.getDisplayName());

var tzlookup = require("tz-lookup");

console.log(tzlookup(42.7235, -73.6931)); // prints "America/New_York"

https://www.npmjs.com/package/geo-tz

const { find } = require('geo-tz')

    console.log(find(47.650499, -122.350070))  // ['America/Los_Angeles']
