Date Difference 1.1

Just give Date Difference two dates and/or times, and it tells you the length of time between them. There are preferences for what units to enable or disable (days, hours, minutes, and/or seconds), and it compensates for the disabled units with the next largest enabled unit (for example, if the difference between the dates is 1 day and 2 hours, but you disable days, then it becomes 26 hours).
