       By default, date pads numeric fields with zeroes.  The following optional flags may follow ''%'':

       -      (hyphen) do not pad the field

       _      (underscore) pad with spaces

       0      (zero) pad with zeros

       ^      use upper case if possible

       #      use opposite case if possible

       After  any  flags  comes  an  optional  field width, as a decimal number; then an optional modifier, which is either E to use the locale''s alternate representations if
       available, or O to use the locale''s alternate numeric symbols if available.

EXAMPLES
       Convert seconds since the epoch (1970-01-01 UTC) to a date

              $ date --date=''@2147483647''

       Show the time on the west coast of the US (use tzselect(1) to find TZ)

              $ TZ=''America/Los_Angeles'' date

       Show the local time for 9AM next Friday on the west coast of the US

              $ date --date=''TZ="America/Los_Angeles" 09:00 next Fri''

DATE STRING
       The --date=STRING is a mostly free format human readable date string such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29 16:21:42" or  even  "next  Thursday".   A
       date  string may contain items indicating calendar date, time of day, time zone, day of week, relative time, relative date, and numbers.  An empty string indicates the
       beginning of the day.  The date string format is more complex than is easily documented here but is fully described in the info documentation.

firefox浏览器下JS的new Date()的值为Invalid Date、NaN-NaN的问题

当我们需要将一串日期字符串转换为具体的Date格式的时候，往往需要用到new Date("xxxx")方法。

当时在IE浏览器下，会遇到这种问题：

new Date(''2016-01-01 00:00:00'')    //却返回这个值Invalid Date，转换失败

但是这个方法却在谷歌浏览器上可以返回正确的结果。

解决方式：最终发现是字符串的格式不被某些浏览器失败，而导致的。

new Date(''2016/01/01 00:00:00'')  //这下就转换正确了Wed Jan 1 00:00:00 UTC+0800 2014

在具体使用的时候，可以通过一些字符串转换的方式，将日期字符串格式转换正确之后，再使用new Date()。

var date="2016-12-12 10:10:10";
date=date.replace(new RegExp(/-/gm) ,"/"); 　　//将所有的''-''转为''/''即可
Date d=new Date(date);

所以，不同的浏览器还是存在差异的，以下列出了所有浏览器都支持的方式。

1 var d = new Date(2011, 01, 07); // yyyy, mm-1, dd  
2 var d = new Date(2011, 01, 07, 11, 05, 00); // yyyy, mm-1, dd, hh, mm, ss  
3 var d = new Date("02/07/2011"); // "mm/dd/yyyy"  
4 var d = new Date("02/07/2011 11:05:00"); // "mm/dd/yyyy hh:mm:ss"  
5 var d = new Date(1297076700000); // milliseconds  
6 var d = new Date("Mon Feb 07 2011 11:05:00 GMT"); // ""Day Mon dd yyyy hh:mm:ss GMT/UTC

getDateDiffNew2(pTime:string) {
    let result;
    let minute:number = 60;
    let hour:number = minute * 60;
    let day:number = hour * 24;
    let month:number = day * 30;
    let now = new Date().getTime()/1000;
    pTime=pTime.replace(new RegExp(/-/gm) ,"/"); 　　//将所有的''-''转为''/''即可
    let old = new Date(pTime).getTime()/1000;
    let nn = parseInt(String(now));
    let oo = parseInt(String(old));
    let diffValue:number = Number(now) - Number(old);
    let monthC:number = diffValue / month;
    let weekC:number = diffValue / (7 * day);
    let dayC:number = diffValue / day;
    let hourC:number = diffValue / hour;
    let minC:number = diffValue / minute;

    if (monthC >= 1) {
      if(monthC > 12)
      {
        result = pTime.substring(0,10);
      }
      else if(monthC == 1)
      {
        result = pTime.substring(5,10);
      }
      else
      {
        result = pTime.substring(5,10);
      } 
    }
    else if (weekC >= 1) {
      result = pTime.substring(5,10);
    }
    else if (dayC >= 1) {
      result = pTime.substring(5,10);
    }
    else if (hourC >= 1) {
      result = Math.round(hourC) + "小时前";
    }
    else if (minC >= 1) {
      result = Math.round(minC) + "分钟前";
    } 
    else
    {
      result = "刚刚";
    } 
    //var b:String = new String(diffValue);
    //var b:string = <string> String(nn) ;
    //var o:string = <string> String(old) ;
    //return b + '':'' + o;
    return result;
  }
