在java中你可以使用这种方法。

   private String getHmaa(long seconds) {
    String string;
    int hours = (int) seconds / 3600;
    int remainder = (int) seconds - hours * 3600;
    int mins = remainder / 60;
    //remainder = remainder - mins * 60;
    //int secs = remainder;

    if (hours < 12 && hours > 0) {
        if (mins < 10) {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? "0" + mins : "0") + " AM");
        } else {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? mins : "0") + " AM");
        }
    } else if (hours >= 12) {
        if (mins < 10) {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? "0" + mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));
        } else {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));

一小时是3600秒，一分钟是60秒，为什么不呢?

<?php

$init = 685;
$hours = floor($init / 3600);
$minutes = floor(($init / 60) % 60);
$seconds = $init % 60;

echo "$hours:$minutes:$seconds";

?>

生产:

$ php file.php
0:11:25

(我没有测试这么多，所以地板可能会有错误)

试试这个:

date("H:i:s",-57600 + 685);

从 http://bytes.com/topic/php/answers/3917-seconds-converted-hh-mm-ss

如果你不喜欢公认的答案或流行的答案，那么试试这个

function secondsToTime($seconds_time)
{
    if ($seconds_time < 24 * 60 * 60) {
        return gmdate('H:i:s', $seconds_time);
    } else {
        $hours = floor($seconds_time / 3600);
        $minutes = floor(($seconds_time - $hours * 3600) / 60);
        $seconds = floor($seconds_time - ($hours * 3600) - ($minutes * 60));
        return "$hours:$minutes:$seconds";
    }
}

secondsToTime(108620); // 30:10:20

任何人在未来寻找这个，这给了最初的海报要求的格式。

$init = 685;
$hours = floor($init / 3600);
$hrlength=strlen($hours);
if ($hrlength==1) {$hrs="0".$hours;}
else {$hrs=$hours;} 

$minutes = floor(($init / 60) % 60);
$minlength=strlen($minutes);
if ($minlength==1) {$mins="0".$minutes;}
else {$mins=$minutes;} 

$seconds = $init % 60;
$seclength=strlen($seconds);
if ($seclength==1) {$secs="0".$seconds;}
else {$secs=$seconds;} 

echo "$hrs:$mins:$secs";
