Is the time zone always at the end of the string? (The time zone doesn't appear at all when I try.)

If it is, you can use the <a href="http://www.w3schools.com/jsref/jsref_slice_string.asp" rel="nofollow">slice method</a> to remove the last four characters of the string (space + 3-character time zone).

As far as I can tell, no browser returns 'EDT' from toLocaleString, on windows anyway,
and only Chrome returns the timezone at all. 

Other platforms may assign the string differently. 

My bigger beef is that Chrome uses a 24 hour clock for local time.

// testing new Date().toLocaleString() (windows 7)

<ul>
<li>Safari 5.0>> Tuesday, June 14, 2011 15:13:43</li>
<li>Chrome 9.0.597.98>> Tue Jun 14 2011 15:15:01 GMT-0400 (Eastern Daylight Time)</li>
<li>Opera 11.01>> 6/14/2011 3:15:37 PM</li>
<li>Firefox 4.0.1>> Tuesday, June 14, 2011 3:16:33 PM</li>
<li>MSIE 8.0>> Tuesday, June 14, 2011 3:16:06 PM</li>
<li>MSIE 9.0>> Tuesday, June 14, 2011 3:17:09 PM</li>
</ul>

They all return the hours:minutes:seconds in a group,
so to exclude anything after the time you could:

<pre><code>var d=new Date().toLocaleString();
var s= d.toLocaleString().match(/^[^:]+(:\d\d){2} *(am|pm)\b/i)[0];

returned value: (Chrome)
Tue Jun 14 2011 15:26:11:11
</code></pre>

Another way is to concat the locale day and time strings, which, surprisingly, does not return the timezone on chrome- but your milage may vary.

<pre><code>var D=new Date();
D.toLocaleDateString()+' '+D.toLocaleTimeString()
</code></pre>

returns Tuesday, June 14, 2011 15:44:35 in Chrome

blocks|key|365414|text|没有办法确定toLocaleString将返回什么；您当然不能保证EDT会出现在运行它的每台机器上，更不用说任何时区的指示了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|365415|来自Mozilla的开发者网络：|365416|365417|+toLocaleString方法在设置日期格式时依赖于基础操作系统。它使用运行脚本的操作系统的格式约定将日期转换为字符串。例如，在美国，月份出现在日期(04/15/98)之前，而在德国，日期出现在月份(15.04.98)之前。如果操作系统与2000年不兼容，并且1900年之前或2000年以上的年份不使用全年，则toLocaleString将返回一个与2000年不兼容的字符串。在转换操作系统未正确格式化的年份时，toLocaleString的行为类似于toString。|blockquote|365418|365419|365420|一种可能的解决方法是使用toLocaleDateString和toLocaleTimeString构造一个自定义日期字符串。|365421|//+Something+to+this+effect:

There is no way to be certain what <code>toLocaleString</code> will return; you certainly couldn't guarantee <code>EDT</code> would show up on every machine that runs it, let alone any indication of timezone.

From Mozilla's developer network:

<blockquote>
 The <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toLocaleString" rel="noreferrer"><code>toLocaleString</code></a> method relies on the underlying operating system in formatting dates. It converts the date to a string using the formatting convention of the operating system where the script is running. For example, in the United States, the month appears before the date (04/15/98), whereas in Germany the date appears before the month (15.04.98). If the operating system is not year-2000 compliant and does not use the full year for years before 1900 or over 2000, toLocaleString returns a string that is not year-2000 compliant. toLocaleString behaves similarly to toString when converting a year that the operating system does not properly format.
</blockquote>

One possible workaround would be to construct a custom date string using <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toLocaleDateString" rel="noreferrer"><code>toLocaleDateString</code></a> and <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString" rel="noreferrer"><code>toLocaleTimeString</code></a>.

<pre><code>// Something to this effect:
var d = new Date();
console.log(d.toLocaleDateString() + " " + d.toLocaleTimeString());
</code></pre>

This generally wouldn't include the time zone in its output, but even this isn't perfect as you can't know what the exact format of the output would be.

Thus, the best solution would be to use a custom date-formatting function:

<pre><code>// Add leading-zeros to numbers less than 10[000...]
function padZ(num, n) {
 n = n || 1; // Default assume 10^1
 return num &lt; Math.pow(10, n) ? "0" + num : num;
}

function formattedDate(d) {
 var day = d.getDate();
 var month = d.getMonth() + 1; // Note the `+ 1` -- months start at zero.
 var year = d.getFullYear();
 var hour = d.getHours();
 var min = d.getMinutes();
 var sec = d.getSeconds();
 return month+"/"+day+"/"+year+" "+hour+":"+padZ(min)+":"+padZ(sec);
}
</code></pre>

For an in-depth look at the available <code>Date</code> methods, check out <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date" rel="noreferrer"><code>Date</code></a> on the MDN.

I'm relatively new to javascript, so this may be a really simple question. Is there an easy way to stop 'EDT' from printing after a date returned with toLocaleString?
Thanks!
