Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• TOD clock conversion in a SPEC stage with the C2T and T2C
  conversion may fail for dates in a leap year.
  The T2C conversion in SPEC fails for Feb 29th in a leap year,
  issuing the FPLCVG644E message. The C2T conversion for a TOD
  clock of Dec 31st in a leap year will incorrectly produce the
  date of the next day.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of CMS Pipelines who use a SPEC    *
  *                 stage with C2T to convert TOD clock values   *
  *                 into human readable time stamp, or T2C to    *
  *                 convert a human readable time stamp into a   *

  ****************************************************************
  The CMS Pipelines code doing the conversion for a SPEC stage
  failed to compute the number of days in a leap year, and was
  incorrectly rejecting Feb 29 as a valid date in a leap year.
  
  The conversion in a SPEC stage is commonly used with the
  current date and time, or times in recent past or near future.
  Customer applications using the C2T and T2C conversion are
  more likely affected in a leap year around Feb 29 and Dec 31.
  

Problem conclusion

• The code computing the number of days in a year has been fixed
  to handle leap years correctly. The check for the number of days
  in the month has been corrected for the month of February in a
  leap year.
