I have a script which calculates how many hours a truck driver has worked/rested in increments of 15 minutes. For a given number of hours I loop around adding 15 minutes to a cursor for each 15 minutes of work/rest. This all works fine until 7 Oct 2012 when adding 15 minutes to 01:45:00 gives a result of 03:00:00 instead of 02:00:00 Here's my code: <?php $diff = 4; // Number of hours difference in units of 15 minutes $cursor = "2012-10-07 00:00:00"; // Start time, midnight on 07 October 2012 for($z=0;$z<$diff/.25;$z++) { print "Cursor = ".$cursor."<br>"; $cursor = date('Y-m-d H:i:s', strtotime( "$cursor + 15 minutes" )); } ?> This is the result: Cursor = 2012-10-07 00:00:00 Cursor = 2012-10-07 00:15:00 Cursor = 2012-10-07 00:30:00 Cursor = 2012-10-07 00:45:00 Cursor = 2012-10-07 01:00:00 Cursor = 2012-10-07 01:15:00 Cursor = 2012-10-07 01:30:00 Cursor = 2012-10-07 01:45:00 /* Jumps to 03:00:00 instead of 02:00:00 */ Cursor = 2012-10-07 03:00:00 Cursor = 2012-10-07 03:15:00 Cursor = 2012-10-07 03:30:00 Cursor = 2012-10-07 03:45:00 Cursor = 2012-10-07 04:00:00 Cursor = 2012-10-07 04:15:00 Cursor = 2012-10-07 04:30:00 Cursor = 2012-10-07 04:45:00 Can anyone help??
