(1*(24*60*60) + 3*(60*60) + 5*(60) + 7)*1000 as value in milliseconds (97507000).
so if millis() gives you 98765432:
it is 98765.432s
or 98765.432/60=1646.0905m or 1646m and (0.0905*60)=5,432s
or 98765.432/3600=27.43484h or 27h and 0.43484*60=26,0905min or 27h 26min and (0.0905*60)=5,432s
same for days, starting with /86400
