blocks|key|1561728|text|上述解决方案的问题是，如果小时、分钟或秒只有一个数字(即0-9)，则时间将是错误的，例如，它可能是2:3:9，但它应该是02:03:09。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1561729|根据this+page的说法，使用Date的"toLocaleTimeString“方法似乎是更好的解决方案。|offset|length|1561730|entityMap|0|LINK|mutability|MUTABLE|url|https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString^0|0|2|9|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

<p>The problem with the aforementioned solutions is, that if hour, minute or second, has only one digit (i.e. 0-9), the time would be wrong, e.g. it could be 2:3:9, but it should rather be 02:03:09.</p>

<p>According to <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString" rel="noreferrer">this page</a> it seems to be a better solution to use Date's "toLocaleTimeString" method.</p>

<p>Pay attention to the zero problem with some of the answers. For example, the timestamp <code>1439329773</code> would be mistakenly converted to <code>12/08/2015 0:49</code>.</p>

<p>I would suggest on using the following to overcome this issue:</p>

<pre><code>var timestamp = 1439329773; // replace your timestamp
var date = new Date(timestamp * 1000);
var formattedDate = ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);

<p>The answer given by @Aron works, but it didn't work for me as I was trying to convert timestamp starting from 1980. So I made few changes as follows</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function ConvertUnixTimeToDateForLeap(UNIX_Timestamp) {
    var dateObj = new Date(1980, 0, 1, 0, 0, 0, 0);
    dateObj.setSeconds(dateObj.getSeconds() + UNIX_Timestamp);
    return dateObj;  
}

document.body.innerHTML = 'TimeStamp : ' + ConvertUnixTimeToDateForLeap(1269700200);</code></pre>
</div>
</div>
</p>

<p>So if you have a timestamp starting from another decade or so, just use this. It saved a lot of headache for me.</p>
