JavaScript 从时间戳获取日期和时间

我将此字段作为网络响应的一部分：

datetime_local: "2015-02-16T19:00:00"

我可以提取日期和时间吗？例如我想显示

February 16th at 7pm

这可能吗？

使用此功能

function getFormattedDate(date)
{
var fortnightAway = new Date(date),
        date = fortnightAway.getUTCDate(),
        hour = fortnightAway.getUTCHours(),
        month = "January,February,March,April,May,June,July,August,September,October,November,December"
      .split(",")[fortnightAway.getUTCMonth()];

    function nth(d) {
      if(d>3 && d<21) return 'th'; // thanks kennebec
      switch (d % 10) {
            case 1:  return "st";
            case 2:  return "nd";
            case 3:  return "rd";
            default: return "th";
        }
    }

return month+" "+date+nth(date) +" at "+(hour<12?hour+"am":(hour-12)+"pm");   
}

称呼它为getFormattedDate("2015-02-16T19:00:00")
