How to convert Moment js date to users local timezone

Question

I use the Moment js and Moment-Timezone frameworks  and have a Moment js date object which is explicitly in UTC timezone  How can I convert that to the current timezone of the browser   var testDateUtc   moment tz  2015-01-30 10 00 00    UTC    var localDate         So it would be fine if I could find out the users local time zone  or alternatively I d like to convert the date object into another data object which just uses the  local timezone   no matter what that actually is

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

var dateFormat    YYYY-DD-MM HH mm ss   var testDateUtc   moment utc  2015-01-30 10 00 00    var localDate   testDateUtc local    console log localDate format dateFormat       2015-30-01 02 00 00    Define your date format    Create a moment object and set the UTC flag to true on the object    Create a localized moment object converted from the original moment object    Return a formatted string from the localized moment object    See  http   momentjs com docs   manipulating local

Use utcOffset function   var testDateUtc   moment utc  2015-01-30 10 00 00    var localDate   moment testDateUtc  utcOffset 10   60     set timezone offset in minutes console log localDate format       2015-01-30T20 00 00 10 00
