/*
  This function takes two js timestamps and calculates the difference
  between the two and returns the difference in a d:h:m format.

  By default, it does NOT round hours or minutes.

  Optional 3rd arg will round UP or DOWN after the first hour and first day.
  Ex: 0:1:12 will be rounded up to 0:2:0 or down to 0:1:0
      1:5:6 will be rounded up to 2:0:0 or down to 1:0:0

  Optional 4th arg will pad the d:h:m value with leading 0's.
  Ex: 0:0:1 can be turned into 00:00:01
