Though, I had to change the format of $str slightly to get it to work on a windows box. Additionally, I tried the following (which also worked): <? $str = "2007-06-17T19:35:00"; $timestamp = strtotime( $str ); $oneMinute = 60; // seconds $oneHour = $oneMinute * 60; $oneDay = $oneHour * 24; for( $i = 1; $i <= 24; $i++ ) { echo $i . ' hours ago: ' . date( 'm/d/Y h:i:s', $timestamp - ( $oneHour * $i )) . '<br>'; } ?> thnx, Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
