This proposal satisfies my concerns.  But we should review and see if it raises any other issues:

> YEARFRAC is currently defined as "Computes the fraction of the number of years between a StartDate and EndDate.
> Basis is the system for determining how many days are in a month or year."
> OK.  So YEARFRAC is A/B where A= number of days between the two dates, using the counting conventions of the basis.  And B is what? A year certainly.  But how many days?  365?  365.25?  Dependent on whether date 1 or date 2 is in a leap year?
