moment JS returns wrong date

Question

I'm passing UTC timestamp to moment js and timezone in order to get back the real date.

This is how I'm doing it:

formatDate: function(dateTime, timezone) {
    var format = 'D-MMM-YYYY';
    return moment.utc(dateTime, format).tz(timezone).format(format);
}

So I would pass on something like formatDate(1399922165, 'America/Los_Angeles'); and it returns 12-Jan-9992 instead of 12-May-2014.

If instead I do it like this:

moment(dateTime).tz(timezone).format(format);

Then it returns 16-Jan-1970.

Thanks to Ian, this ended up being the solution.

moment.unix(dateTime).tz(timezone).format(format);

Any ideas?

Thanks to Ian, this ended up being the solution.

moment.unix(dateTime).tz(timezone).format(format);

I was trying moment.utc() instead of moment.unix() .

The strange results came from moment.utc(datetime, format) expecting datetime to match format . However, it's important to note that moment.utc(datetime) still returns 1970 year result so it still wouldn't have returned the desired result even without the format.
