How to get total web page response time from a HAR file?

Question

In the following image, I want the total response time from the webpage. I can\'t seem to find it in the file sample HAR file, i.e. 38.79s in this case. Does anyone know how

Based on @Sebastian Zartner's answer and the Google sample, the following is an Java attempt:

public class ParseHarFile {

     public static void main(String[] args) {
         String fileName = "www.google.com.har";

         ReadHarFile(fileName);
    }

    public static void ReadHarFile(String fileName){

         File f = new File("C:\\Users\\Administrator\\Desktop\\test_files\\" + fileName);
         HarFileReader r = new HarFileReader();

         try
         {
             System.out.println("Reading " + fileName);
             HarLog log = r.readHarFile(f);

             // Access all pages elements as an object
              HarPages pages = log.getPages();

              long startTime =   pages.getPages().get(0).getStartedDateTime().getTime();

              System.out.println("page start time: " + startTime);

             // Access all entries elements as an object
             HarEntries entries = log.getEntries();

             List hentry = entries.getEntries();

             long loadTime = 0;

             int entryIndex = 0;
             //Output "response" code of entries.
             for (HarEntry entry : hentry)
             {
                 System.out.println("entry: " + entryIndex);
                 System.out.println("request code: " + entry.getRequest().getMethod()); //Output request type
                 System.out.println("    start time: " + entry.getStartedDateTime().getTime()); // Output start time
                 System.out.println("    time: " + entry.getTime()); // Output start time

                 long entryLoadTime = entry.getStartedDateTime().getTime() + entry.getTime();

                 if(entryLoadTime > loadTime){
                     loadTime = entryLoadTime;
                 }

                 System.out.println();
                 entryIndex++;
             }

             long loadTimeSpan = loadTime - startTime;
             System.out.println("loadTimeSpan: " + loadTimeSpan);

             Double webLoadTime = ((double)loadTimeSpan) / 1000;
             double webLoadTimeInSeconds = Math.round(webLoadTime * 100.0) / 100.0; 
             System.out.println("Web Load Time: " + webLoadTimeInSeconds) ;

         }
         catch (JsonParseException e)
         {
             e.printStackTrace();
             System.out.println("Parsing error during test");
         }
         catch (IOException e)
         {
             e.printStackTrace();
             System.out.println("IO exception during test");
         }
     }

}
