/////CUSTOM FORMAT OUTPUT FUNCTIONS BELOW//////////////////////////////

 

//Create your own custom format function to pass into cdtime.displaycountdown()

//Use arguments[0] to access "Days" left

//Use arguments[1] to access "Hours" left

//Use arguments[2] to access "Minutes" left

//Use arguments[3] to access "Seconds" left

//For example, if "baseunit" is set to "hours", arguments[0] becomes meaningless and contains "n/a"

//For example, if "baseunit" is set to "minutes", arguments[0] and arguments[1] become meaningless etc
