$timestamp = "2013-09-30 01:16:06";
echo date("F jS, Y", strtotime($timestamp)); //September 30th, 2013
Note the use of S
to get the english ordinal suffix for the day.
Since you're already using strtotime
if you need a human readable data for the current time you can just use the keyword "now" as in strtotime("now")
