You have seen a lots of Websites are displaying past times in days, hours and minutes. If you want to do this yourself, you can use the TIMEDIFF() SQL function. Note that the TIMEDIFF() function can only handle time range within 839 hours (about 33 days). So it works only for past times within one month or so.

The following tutorial exercise shows you how to use TIMEDIFF() to present a past time in days, hours, and minutes:

<?php
  include "mysql_connection.php";

  $pastTime = "2006-06-29 04:09:49";

  $sql = "SELECT HOUR(timeDiff) AS hours,"
    . " MINUTE(timeDiff) AS minutes FROM ("
    . " SELECT TIMEDIFF(NOW(), '".$pastTime."')"
    . " AS timeDiff FROM DUAL) subQuery";
  print("SQL = $sql\n");
  $rs = mysql_query($sql, $con);
  while ($row = mysql_fetch_assoc($rs)) {
    print("$pastTime was ".$row['hours']." hours, "
      . $row['minutes']." minutes ago.\n");
  }
  mysql_free_result($rs);

  $sql = "SELECT (HOUR(timeDiff) DIV 24) AS days,"
    . " (HOUR(timeDiff) MOD 24) AS hours,"
    . " MINUTE(timeDiff) AS minutes FROM ("
    . " SELECT TIMEDIFF(NOW(), '".$pastTime."')"
    . " AS timeDiff FROM DUAL) subQuery";
  print("SQL = $sql\n");
  $rs = mysql_query($sql, $con);
  while ($row = mysql_fetch_assoc($rs)) {
    print("$pastTime was ".$row['days']." days, "
      . $row['hours']." hours, "
      . $row['minutes']." minutes ago.\n");
  }
  mysql_free_result($rs);

  mysql_close($con); 

If today is you run this script, you will get something like this:

SQL = SELECT HOUR(timeDiff) AS hours, 
   MINUTE(timeDiff) AS minutes FROM (
   SELECT TIMEDIFF(NOW(), '2006-06-29 04:09:49') 
   AS timeDiff FROM DUAL) subQuery

2006-06-29 04:09:49 was 115 hours, 2 minutes ago.

SQL = SELECT (HOUR(timeDiff) DIV 24) AS days, 
   (HOUR(timeDiff) MOD 24) AS hours,
   MINUTE(timeDiff) AS minutes FROM (
   SELECT TIMEDIFF(NOW(), '2006-06-29 04:09:49')
   AS timeDiff FROM DUAL) subQuery

2006-06-29 04:09:49 was 4 days, 19 hours, 2 minutes ago.

Warning again, this script only works if the past time is less than 33 days ago.
