PH41540: INTEGER-OF-FORMATTED-DATE GIVES INCORRECT RESULTS FOR AMODE64

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The INTEGER-OF-FORMATTED-DATE intrinsic function returns an
  incorrect value if January 4th of the given year is not a Monday
   and accepts week 00 as valid. As per the ISO 8601 standard, the
   first week of the year is week 01
  and includes January 4th of that year. When January 4th of given
  year lands on Tuesday, Wednesday, or Thursday and the
  INTEGER-OF-FORMATTED-DATE is used to convert a date in
  integer-week-day format into an integer date, the result is 7
  days higher
  than the correct value. Additionally, when January 4th of given
  year lands on Sunday, Saturday, or Friday then the result was
  365 days lower than the correct value.
