code: def utime_delta(days=0, hours=0, minutes=0, seconds=0):
      
      return (days * DAY) + (hours * HOUR) + (minutes * MINUTE) + (seconds * SECOND)
docs: Gets time delta in microseconds.
  
      Note: Do NOT use this function without keyword arguments.
      It will become much-much harder to add extra time ranges later if positional arguments are used.
