First you need to convert both days into timestamps, which are much easier
to deal with. you get todays timestamp from mktime(); to convert the textual
date representation into a timestamp you could use strtotime().
the code would look like this:
$today = mktime();
$created = strtotime($rs['lastBuildDate']); // This is the March 6...
now that you have both dates as timestamps, their difference in seconds is
simply:
$diff = $today - $created;
Now just do the math to convert the seconds to days, hours, minutes. Just
divide it by 60, 60, 24 etc.
