wtz.go is a Go library to portablly handle the time zone names used in Windows. They sometimes appear to you outside the Windows environment, for example, when manipulating Office 365 calendar events with msgraph.go (see dateTimeTimeZone resource type). wtz.go helps you with translating them to/from time.Location with IANA time zone names.

Playground: https://play.golang.org/p/l9CeGUXNwZP

package main

import (
	"fmt"
	"github.com/yaegashi/wtz.go"
	"time"
)

func main() {
	var n string
	var l *time.Location

	n = "Tokyo Standard Time"
	l, _ = wtz.LoadLocation(n)
	fmt.Printf("%v -> %v\n", n, l)

	l, _ = time.LoadLocation("America/Los_Angeles")
	n, _ = wtz.LocationToName(l)
	fmt.Printf("%v -> %v\n", l, n)
}

The mapping table is based on windowsZones.xml from Unicode CLDR. The table generator is inspired by genzabbrs.go.
