Moment.JS display formatted time from named timezone

Question

I am trying to display a time in the current named timezone using moment timezone.

The time is stored in the database in UTC as 2014-07-22 11:11:06. Whatever I try I cannot display the time as 12:11 even though the named timezone is Europe/London.

var timestamp = 1406023866000; // converted from database stored as UTC 2014-07-22 11:11:06 var zone = tz.name(); // Europe/London var utc = moment(timestamp); // create a moment from the timestamp var time = utc.tz(zone); // _d: Date {Tue Jul 22 2014 12:11:06 GMT+0100 (GMT Standard Time)} // _f: undefined // _i: 1406023866000 formatted = time.format('h:mma'); // 11:11am - should be 12.11pm because of BST

Have you tried providing a string to tz.name? Explicitly name your timezone? — Upperstage

Just tried that and made no difference var time = utc.tz("Europe/London"); — Asa Carter

Assuming that your timestamp is in milliseconds, 1406023866000 = GMT: Tue, 22 Jul 2014 10:11:06 GMT.

Changing the timezone in php from Europe/London to UTC seems to have fixed the issue somehow.

Congrats. When I converted your timestamp - using the website above - the ceonverted date was ONE HOUR EARLIER than you posted in your question. fyi

Yeh it was driving me crazy. I assumed that date('U', strtotime($conversation_data['updated'])) * 1000; was creating the timestamp in UTC.
