computeDifference??

I do not get the part with iUnit (5=days? 4=hours?)
public static final double computeDifference(CDateTime cdt1,
CDateTime cdt2,
int iUnit)

Computes the difference between two given datetime values as a fraction for the requested field.

Parameters:
cdt1 - The first datetime value
cdt2 - The second datetime value
iUnit - The field with respect to which the difference is being computed as a fraction
Returns:
The fractional difference between the two specified datetime values


Code:
System.out.println(cstart.toString());
System.out.println(cend.toString());
System.out.println(CDateTime.computeDifference(cend, cstart,-1));//???
System.out.println(CDateTime.computeDifference(cend, cstart,1));//???
System.out.println(CDateTime.computeDifference(cend, cstart,2));//???
System.out.println(CDateTime.computeDifference(cend, cstart,3));//???
System.out.println(CDateTime.computeDifference(cend, cstart,4));//???
System.out.println(CDateTime.computeDifference(cend, cstart,5));//???
System.out.println(CDateTime.computeDifference(cend, cstart,6));//???
System.out.println(CDateTime.computeDifference(cend, cstart,7));//???
System.out.println(CDateTime.computeDifference(cend, cstart,8));//???
