function process(element){
var text = element.innerText;
var pattern = /\((\d+):(\d{2})\)/;
var results = text.match(pattern);
if(results && results.length == 3)
   return results[1]*60 + results[2]*1;

for(var i=0; i < links.length; i++){
totaltime += process(links[i]);
}

totaltime/3600; //time in hours
