Description: This function returns the amount of time between two dates / date fields in Clarizen, with the option of choosing the interval unit of time.
Use: Like DateSubtract(), this function is important because it’s useful to see the actual amount of time between two dates in the system. Unlike DateSubtract(), which gives you only the option to see the difference in days (working or calendar), DateDiff() gives you the option of more duration intervals, like weeks, months, or years.
