投稿された時刻を返す関数がありますが、少し問題があるようです。最初は $timeAgo1 は問題なく動作しますが、2 回目は $timeAgo2 が負の秒数を返すようです。それはどのように起こっていますか？

<?php

//*****************************************************START OF FUNCTION
function timeAgo($time_ago) {

    $time_ago = strtotime($time_ago);
    $cur_time = time();
    $time_elapsed = $cur_time - $time_ago;
    $seconds = $time_elapsed ;
    $minutes = round($time_elapsed / 60 );
    $hours = round($time_elapsed / 3600);
    $days = round($time_elapsed / 86400 );
    $weeks = round($time_elapsed / 604800);
    $months = round($time_elapsed / 2600640 );
    $years = round($time_elapsed / 31207680 );

    echo $seconds."<br>";
    if ($seconds <= 60) {
        return "just now";
    } //end of if ($seconds <= 60)

    else if ($minutes <=60) {
        if ($minutes == 1) {
            return "one minute ago";
        } //end of else if ($minutes <=60)
        else {
            return "$minutes minutes ago";
        } //end of else not ($minutes == 1)
    } //end of else if ($minutes <= 60)


    else if ($hours <= 24) {
        if ($hours == 1) {
            return "an hour ago";
        } //end of if ($hours == 1)
        else {
            return "$hours hours ago";
        } //end of else not ($hours == 1)
    } //end of else if ($hours <= 24)


    else if ($days <= 7) {
        if ($days == 1) {
            return "yesterday";
        } //end of else if ($days <= 7)
        else {
            return "$days days ago";
        } //end of else not ($days == 1)
    } //end of else if ($days <= 7)

    else if ($weeks <= 4.3) {
        if ($weeks == 1) {
            return "a week ago";
        } //end of if ($weeks == 1)
        else {
            return "$weeks weeks ago";
        } //end of else not ($weeks == 1)
    } //end of else if ($weeks <= 4.3)


    else if ($months <= 12) {
        if ($months == 1) {
            return "a month ago";
        } //end of if ($months == 1)
        else {
            return "$months months ago";
        } //end of else not ($months == 1)
    } //end of else if ($months <= 12)

    else {
        if ($years == 1) {
            return "one year ago";
        } //end of if ($years == 1)
        else {
            return "$years years ago";
        } //end of else not ($years == 1)
    } //end of last else

スクリプトの先頭にあるタイムゾーンを、チェック対象の元の日付と同じ日付に設定します。例:

date_default_timezone_set('America/Los_Angeles');

私は2つの異なるサーバーを使用し、結果は

166733
20094
2 days ago
6 hours ago

サーバーが別の場所にある可能性があるため、time();関数は予想とは異なるタイムスタンプを示します。

2 回目の timeAgo のタイムスタンプは 1455290705 であるため、サーバーはおそらく 1455290705 よりも大きい/だった場所に配置されています。
