You can use geolocator.js for easily getting timezone and more...
It uses Google APIs that require a key. So, first you configure geolocator:
geolocator.config({
language: "en",
google: {
version: "3",
key: "YOUR-GOOGLE-API-KEY"
}
});
Get TimeZone if you have the coordinates:
geolocator.getTimeZone(options, function (err, timezone) {
console.log(err || timezone);
});
Example output:
{
id: "Europe/Paris",
name: "Central European Standard Time",
abbr: "CEST",
dstOffset: 0,
rawOffset: 3600,
timestamp: 1455733120
}
Locate then get TimeZone and more
If you don't have the coordinates, you can locate the user position first.
Example below will first try HTML5 Geolocation API to get the coordinates. If it fails or rejected, it will get the coordinates via Geo-IP look-up. Finally, it will get the timezone and more...
var options = {
enableHighAccuracy: true,
timeout: 6000,
maximumAge: 0,
desiredAccuracy: 30,
fallbackToIP: true, // if HTML5 fails or rejected
addressLookup: true, // this will get full address information
timezone: true,
map: "my-map" // this will even create a map for you
};
geolocator.locate(options, function (err, location) {
console.log(err || location);
});
Example output:
{
coords: {
latitude: 37.4224764,
longitude: -122.0842499,
accuracy: 30,
altitude: null,
altitudeAccuracy: null,
heading: null,
speed: null
