Any way to parse a time string using Moment.js but ignore timezone info?

Question

Given the volume of Timezone questions, I would have thought to be able to find the answer to this issue, but haven\'t had any success.

Is there a way using mo

Answer 1

Momentjs default logic will format the given time with local timezone. To format original date, I wrote a function:

Answer 2

I know I'm late to the party, I had the same question and my searches didn't bring me any closer. I broke down and read the documentation and there is an option in moment for a String + Format:

String + Format docs

moment(String, String);

moment(String, String, String);

moment(String, String, Boolean);

moment(String, String, String, Boolean);

and more words, then this:

Unless you specify a time zone offset, parsing a string will create a date in the current time zone.

moment("2010-10-20 4:30",       "YYYY-MM-DD HH:mm");   // parsed as 4:30 local time
moment("2010-10-20 4:30 +0000", "YYYY-MM-DD HH:mm Z"); // parsed as 4:30 UTC

The part that gave me pause was the example that was used to parse local time omitted the +0000, which lead me to think the input string needed to have that removed, but it doesn't.

example:

var time = "2012-12-31T00:00:00+0000";
var x = moment(time); // Sun Dec 30 2012 19:00:00 GMT-0500
var y = moment(time,'YYYY-MM-DD'); //Mon Dec 31 2012 00:00:00 GMT-0500

Answer 3

The best way is to use:

dt = moment("Wed Sep 16 2015 18:31:00 GMT-0400", "ffffd MMM DD YYYY HH:mm:ss GMT-0400",true);

And to display convert again to desired timezone:

 dt.utcOffset("-04:00").toString()
 output > Wed Sep 16 2015 18:31:00 GMT-0400

Answer 4

I solved this by supplying a format as the second argument, and using Moment's method of escaping characters, and wrapped square brackets around the timezone.

moment("2016-01-01T05:00:00-05:00", "YYYY-MM-DDTHH:mm:ss[Z]").startOf("hour").format()

This will still create moment objects using your local time zone, but it won't do any sort of auto-timezone calculation. So the above example will give you 5am regardless of timezone supplied.
