timezonemapper

Golang lib that converts from GPS coordinate latitude/longitude to timezone string.

Translated from java version, see https://github.com/drtimcooper/LatLongToTimezone .

Install

go get -u github.com/zsefvlol/timezonemapper

Usage

package main

import (
	"fmt"
	"github.com/zsefvlol/timezonemapper"
	"time"
)

func main() {
	// Get timezone string from lat/long
	timezone := timezonemapper.LatLngToTimezoneString(39.9254474,116.3870752)
	// Should print "Timezone: Asia/Shanghai"
	fmt.Printf("Timezone: %s\n", timezone)
	// Load location from timezone
	loc, _ := time.LoadLocation(timezone)
	// Parse time string with location
	t, _ :=time.ParseInLocation("2006-01-02 15:04:05", "2010-01-01 00:00:00", loc)
	// Should print
	// 2010-01-01 00:00:00 +0800 CST
	// 2009-12-31 16:00:00 +0000 UTC
	fmt.Println(t)
	fmt.Println(t.UTC())
}

Functions

func LatLngToTimezoneString

func LatLngToTimezoneString(lat, lng float64) string

LatLngToTimezoneString converts from GPS coordinate latitude/longitude to timezone string, for example: "Asia/Shanghai". Invalid or unknown timezone will fall back to empty string "". In that case, if you get location by time.LoadLocation(timezone), an UTC location will be returned.
