Re: How do you change the Freshness of post date format?
Remember that the date will be relative to worldwide visitors unless you list the timezone (which will be meaningless to people far outside the timezone).
What I do on some code is list the freshness in plain english but make the title of the element the original time.
<span class=timetitle title="<?php echo date("r",strtotime($topic->topic_time)); ?>"><?php topic_time(); ?></span>
Then when you mouse over the “3 days ago” it will show you the original time (in mysql format which can be changed). Then use CSS to make a light underline so the user knows it has some kind of function.
