Transformar Countdown em Countup

Pessoal, estou com um contador que o cliente gostou muito do layout, mas é um countdown. É possível transformar em countup?

function JBCountDown(settings) {
 var glob = settings;

 function deg(deg) {

 glob.minutes = 60 - Math.floor((((glob.endDate - glob.now) % 86400) % 3600) / 60) ;
 glob.seconds = 60 - Math.floor((glob.endDate - glob.now) % 86400 % 3600 % 60);

 if (glob.now >= glob.endDate) {
 return;
 }
