Create a local date from a UTC date string in Moment.js

问题

Given a UTC date string (formatted: YYYYMMDDHHmmss) I'd like to create a date with the local timezone using Moment.js. I have tried the following:

var utcDateStr = '20140101120000';
var localDate = moment.utc(utcDateStr, 'YYYYMMDDHHmmss');

//actual: true
//desired: false
console.log(localDate._isUTC)

//actual: "Wed Jan 01 2014 12:00:00 GMT+0000"
//desired: "Wed Jan 01 2014 07:00:00 GMT-0500"
console.log(localDate.toString())

How do I create a date that is formatted in the local time zone by default when I call toString()?

回答1:

Just use the .local() function, added in version 1.5.0.

var localDate = moment.utc(utcDateStr, 'YYYYMMDDHHmmss').local();

回答2:

// UTC time
var utcDateStr = '20140101120000';

// First way
var offset = moment().utcOffset();
var localtime = moment.utc(utcDateStr,'YYYYMMDDHHmmss').utcOffset(offset);

// Another way
var anotherLocaltime= moment.utc(utcDateStr, 'YYYYMMDDHHmmss').local();

Both the way works just fine... See the JsFiddle
