Is there a way to see the "cmi.core.total_time" value in a course?

Ok i figure out how to see the "cmi.core.total_time".

var lmsAPI = parent;

var Tempo = lmsAPI.GetPreviouslyAccumulatedTime();

var player = GetPlayer();

player.SetVar('tempo',Tempo);

But now i need to see this value update during the course.

Any thoughts?

I tried to send the lmsAPI.SaveTime during the course and them execute the code above, but is doesn't seem to work.

 var lmsAPI = parent;

var player = GetPlayer();

lmsAPI.SaveTime();
