max_execution_time = 0

hi. I am getting this error in my script

Fatal error: Maximum execution time of 60 seconds exceeded in C:\wamp\www\gblog\index.php on line 83

I am using wamp on Windows 7 and running the script with the url
http://localhost/gblog/index.php?startdate=1/1/2011&enddate=1/2/2011&keywords=Nikkei

The script is attached.
Can anyone explain what is wrong?
