Convert Epoch time to human readable with specific timezone

rated 0 times [ 190] [ 7] / answers: 1 / hits: 27163 / 7 Years ago, fri, may 19, 2017, 12:00:00

To convert epoch dateTime to human readable , using a simple new date(1495159447834) will suffice.

The problem I'm encountering now is that for my hybrid application, if the user set the time-zone in his phone date time setting to lets say GMT +12:00 ,the human readable dateTime will be different from what I would want the user to have and I would want him/her to follow the server timezone.

Thus , how would I convert the epoch number to a specific given timezone in a human readable format.

I have tried example like:

var test= new Date('1495159447834 GMT+0800').toString();

and it returns me an Invalid Date.

If possible, I would want this without any libraries. I have looked through the answers here and I believe that I could not find any answers I'm looking for. If there is any previously answered question with the same topic, do let me know and I will close this question!

You can use offset to convert your current datetime to a specific timezone.

function convertEpochToSpecificTimezone(timeEpoch, offset){

    var d = new Date(timeEpoch);

    var utc = d.getTime() + (d.getTimezoneOffset() * 60000);  //This converts to UTC 00:00

    var nd = new Date(utc + (3600000*offset));

    return nd.toLocaleString();

}

// convertEpochToSpecificTimezone(1495159447834, +3)

The offset will be your specific timezone. Example: GMT +03:00, your offset is +3. If GMT -10:00, offset is -10
