The 'Times' field when entering 1/60 rounds to a 4 decimal precision. This makes the result .0167. When applying this result to the time on a production order the extended value is 'off' from the expected value. For example:

15 minutes = .25 hours, BUT
in D365 15 minutes = .2505 hours.

The display in all the view calculation details is to 2 decimal precision so when one tries to do the math .25 x rate, the result is not the displayed result.

This may seem like a small issue but when dealing with large metals manufacturers who do all their costing in lbs, this can creep up to a large number of dollars depending on the number of locations, number of shifts running etc. The amount can become material over the course of a year.
