Good day.  I would appreciate some assistance/clarification wrt the Compensation Rule in Expense Rules - Allowances: 

Two fields specifically: “Latest Departure” and “Earliest Return”.  The description for “Latest Departure” is “….. employee is required to depart at a time later than the time given in this field.  The description for “Earliest Return” is “…..employee is required to return from travel at a time earlier than the time given in this field.

What would make most sence ito times to put in these respective fields if time of departure/return is not so important?  In my scenario allowance is calculated based on nights away from home/days in foreign country.  It doesn’t really matter what time the Employee departs/returns, as long as time was spent away from home.  

Thank you.
