DateTime operators testing error breakdown (CqlDateTimeOperatorsTest)

CqlDateTimeOperatorsTest fails commentary:

1. "passCount": 274,
   "skipCount": 5,
   "failCount": 38,
   "errorCount": 0

2. Failing tests:
   A.
   DateTimeAddYearInWeeks Engine evaluates DateTime(2018, 5, 23) + 52 weeks to be "@2019-05-23T". It should evaluate to "@2019-05-22T"
   52 weeks = 364 days
   Adding 364 days to 2018-05-23 (2018 is not a leap year) lands one day before the same calendar date the next year
   See https://github.com/cqframework/clinical-reasoning/issues/883#issue-3793517124.

   These fail the same way
   DateTimeLeapDayAddYearInWeeks
   DateTimeLeapYearAddYearInWeeks
   DateTimeSubtractYearInWeeks
   DateTimeLeapDaySubtractYearInWeeks
   DateTimeLeapYearSubtractYearInWeeks

B.
(interval differences)
DateTimeDurationBetweenUncertainInterval
DateTimeDurationBetweenUncertainInterval2
DateTimeDurationBetweenUncertainAdd
DateTimeDurationBetweenUncertainSubtract
DateTimeDurationBetweenUncertainMultiply

    DateTime2
    DateTimeSubtract5Seconds
    DateTimeSubtract15HourPrecisionSecond

(actual === 1 vs 0)

    DurationInDaysAA

(differing times)
    DateTimeAdd5Hours                   (actual missing 10 in time)

    DateTimeMinute                      (actual missing 20:50 in time)
    DateTimeDurationBetweenYear         (actual is 5 and expected is an interval)
    DateTimeSubtract5Hours              (actual missing 05 in time)
    DateTimeSubtractHoursUnderflow      (actual missing 23 in time)
    DateTimeSubtract5Minutes            (actual missing 05:05 in time)
    DateTimeSubtractMinutesUnderflow    (actual missing 04:59 in time)
