Well, if you want to do the comparison in PHP, you can select out all of
the rows and loop through them all. Use UNIX_TIMESTAMP(column_name) in
your query to get out the unix timestamp of the date column, instead of
the mysql format. Then..

$now = time();
if($now - $db_time > 3600)
        //more than an hour old

You could do it in your query like this:

SELECT * FROM your_table WHERE db_time_column < NOW() - INTERVAL 1 HOUR;

That'll return all rows that have a db_time_column that's more than an
hour old. Adapt that to an update or delete query and you're good to go.
