coordinate-tz

Coordinate - Time Zone map

Takes a latitude and longitude and returns the IANA Time Zone name of the timezone that coordinate is in.

This can be used with the zoneinfo module to get the current time at that coordinate

Example

var sys = require('util');
var CoordinateTZ = require('coordinate-tz'),
	zoneinfo = require('zoneinfo'),
    TZDate = zoneinfo.TZDate;


var latitude = 52.5,
	longitude = 13.3,
	query = CoordinateTZ.calculate(latitude,longitude);

var d = new TZDate();
d.setTimezone(query.timezone);
sys.puts(d);
