Problem with CraigList Checker

[mr_anderson]

Hi
I am trying to build an application that checks whether there has been a new post in a specific craigslist section "Computers for example"
so I am using the getLastModified() from the HttpUrlConnection Class (the code is shown below), when I test this code on other websites it works just fine, but with craigslist website it keeps telling me there is an update and when I check I find no update, so any idea about why is it behaving like that?

import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Date;

public class Main{
  public static void main(String args[]) throws Exception {
    URL url = new URL("http://orlando.craigslist.org/sya/");
    HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();

    long date = httpCon.getLastModified();
    if (date == 0)
      System.out.println("No last-modified information.");
    else
      System.out.println("Last-Modified: " + new Date(date));

 }
}

Thank you and Regards.
Anderson.

Can't that date be somewhere in the past? (unequal to zero)

kind regards,

Thank you for your reply, I should have said my code is included in a while(true) loop which performs the previous command each 5 seconds so it keeps checking.
