browser-tz

Timezone specific manipulation of datetime strings

Designed to be used on top of another library. Initial implementation is build on top of moment-timezone

Motivation

This is a set of minimal operation needed to deal with timezone in javascript. It focuses on only having one canonical representation of a time, namely an ISO8601 string.

Example

var Timezone = require("browser-tz")
var timezoneData = require("moment-timezone/moment-timezones.json")

var tz = Timezone(timezoneData)

var today = new Date().toISOString()
// convert an ISO GMT string to an ISO string with the correct
// offset for that time in New York
var todayInNewYork = tz.IsoString(today, "America/New_York")

// To a timezone operation of adding a day to a day
// within a given time. This either add's a GMT day or +-1 hour
// based on whether a DST change happens during that day in
// new york
var tomorrowInNewYork = tz.addDay({
  iso: todayInNewYork,
  timezone: "America/New_York"
}, 1)

Installation

npm install browser-tz
