Moment.js: the result is always "a few seconds ago" in firefox / ie

Question

I am from UTC +8 timezone, and when I try to convert 2014-06-04 12:51:53 +0800/ from Rails / timestamp to my timezone. But it only works in chrome, and all other users cannot use the UTC time zone. And the result is always a few seconds ago. Here is how I use it:

window.updateTimestamps = (elements)->
  moment.lang('mn')
  moment().tz("Asia/Ulaanbaatar").format()
  elements.each( ->
    timestamp = moment(new Date($(@).data('datetime')))
    $(@).html(timestamp.fromNow())
  )


$(document).on('ready', ->

  moment.tz.add
    zones:
      "Asia/Ulaanbaatar": [
        "7:7:32 - LMT 1905_7 7:7:32"
        "7 - ULAT 1978 7"
        "8 Mongol ULA%sT"
      ]

    rules:
      Mongol: [
        "1983 1984 3 1 7 0 0 1 S"
        "1983 1983 9 1 7 0 0 0"
        "1985 1998 2 0 8 0 0 1 S"
        "1984 1998 8 0 8 0 0 0"
        "2001 2001 3 6 8 2 0 1 S"
        "2001 2006 8 6 8 2 0 0"
        "2002 2006 2 6 8 2 0 1 S"
      ]
    links: {}

Here is the HTML I'm trying to convert:

<abbr class="time-ago" data-datetime="2014-06-04 12:51:53 +0800"></abbr>

Here is the code:

  timeAgos = $('abbr.time-ago')
  window.updateTimestamps(timeAgos)
  setInterval(window.updateTimestamps, 60000, timeAgos)

Thanks for the answer. I have no idea? Plz help me :)

Javascript moment.js . ISO

>>> moment("2014-06-04 12:51:53 +0800").fromNow()
"a few seconds ago"
>>> moment("2014-06-04T12:51:53+0800").fromNow()
"7 days ago"

:

>>> moment("2014-06-04 12:51:53 +0800", "YYYY-MM-DD hh:mm:ss +ZZ").fromNow()
