Data Scraping/Checking Project in PERL with cron

You will need to write a script in perl. For certain web addresses, the script must access these pages, identify a date and time that will be presented on the web page, and then perform a macro of that will consist of visitng three consecutive webpages and scraping some data on the final webpage. The timing of this scraping is very important, and it is dependent upon the date and time that is recongnized on the first webpage (ie perform scrape at 30 seconds, 5 minutes, and 1 day after the date and time recongnized). The results of the database must be written to a mysql database. The script must be in PERL. There will also need to be a webform where I will addd the URLS to the database that will need to have this scrape preformed on it.
