As per the Accountants approach the cost $6 million of the expensisive equipment is spread over as $1.2 million per month during the five months of Jan., Feb., Mar., Apr., and May. The Project manager needs the equipment before January 1 therefore the expenditure of $6 million needs to be booked before January 1 or on January 1. The cost variance/ variations may be distorted in case the periods of actual expenditure and the periods under which it is booked differ. Further time value of money and budget requirements (actual) may not give correct picture for Project management perspective.
