Is there a way to convert a UTC string of the format "11/30/2016 3:05:24 AM" to browser based timezone(say PST) in javascript without using third-party libraries/scripts like moment.js ?
Example - If the timezone is IST(Indian Standard Time) which is 5 hours and 30 minutes ahead of UTC the output should be 11/30/2016 8:35:24 AM
It would be best if you use moment.
var localTimeInUTC = moment.utc('11/30/2016 3:05:24 AM','MM/DD/YYYY HH:mm:ss A').toDate();
localTime = moment(localTimeInUTC).format('YYYY-MM-DD HH:mm:ss A');
console.log(localTime); // It will be in your browser timezone
in simple with moment.
moment.utc(utcDateTime, utcDateTimeFormat).local().format(specifiedFormat)
Okay Now you cleared that you want to do without third party libraries then also it is possible.
or Simple way without thirdparty library
var dateStr = '11/30/2016 3:05:24 AM';
var date = new Date(dateStr + ' UTC');
console.log(date.toString());
Demo here
You could do something like this.
var dp = "11/30/2016 3:05:24 AM".split(/[/: ]/);
var dateLocale = new Date(Date.UTC(dp[2], dp[0]-1, dp[1], (dp[3]%12 + (dp[6]=='PM' ? 12 : 0)), dp[4], dp[5]));
console.log(dateLocale.toString());Split the dates in components and pass the individual parts in Date.UTC function which returns the number of milliseconds since January 1, 1970, 00:00:00 UTC. See Date.UTC
Create a new date object passing this value and it will return the date in local timezone.
date.toLocaleString()but I'd suggest usingmoment.
