The quake-USA-test.php script has a one-line change to fix the date problem (the USGS site changed a bit leading to a change in a regex for the script).
Line 153 was
preg_match('|<FONT COLOR="#CC0000">(.*)<BR>|Usi',$html,$updated);
and now is changed to
preg_match('|<FONT COLOR="#CC0000">(.*)<BR/>|Usi',$html,$updated);
You can change your copy of the script, or download (and customize) the updated copy at
