VALUE("16:48:00") - VALUE("12:00:00") evaluates to 0.19999999999999996
due to standard IEEE-754 floating-point subtraction error, not 0.2.
Add precision: 10 to the Assert.Equal — well within the actual error
magnitude (1e-16) and matching the test's intent (the time-fraction
should be 0.2 to within meaningful precision).
