moment（）。format（…）在某些设备上返回本地时间，在其他设备上返回UTC

Question

I have a cordova app. To load data from a server, I send as parameters the local time and the Unix timestamp:

var timestamp = Math.floor(date.getTime() / 1000);
var localtime = moment().format("YYYY-MM-DDTHH:mm:ss");

Now I saw that on some devices, localtime is not "local time" but it looks like UTC. From my logs:

2017-11-28 08:33:08 [...] URL/timestamp/1511879588/localtime/2017-11-28T14:33:08

The first date/time is "Chicago" (GMT-6), but the device was in New York (GMT-5) and on a screenshot I saw that it shows 9:33 as time (in the Android system), so this is correct.

On my devices (Android and iOS), localtime is correct, ie, the same as the system time.

What could be wrong here, why is it sometimes "local time" and sometimes UTC?

Answer 1

Please try this:

var timestamp = Math.floor(date.getTime() / 1000);
var localtime = moment.parseZone(new Date()).local().format("YYYY-MM-DDTHH:mm:ss");
