IV64572: JAVA.TEXT.SIMPLEDATEFORMAT.FORMAT() INCORRECTLY FORMATS YEAR PATTERN

APAR status

• Closed as program error.

Error description

• While formatting the year pattern, the API
  SimpleDateFormat.format() gives two digit year value for
  patterns 'y' and 'yyy'.
  

Local fix

Problem summary

• The Java API specification mentions about the way to format the
  year patterns.
  
  Year:For formatting, if the number of pattern letters is 2, the
  year is truncated to 2 digits; otherwise it is interpreted as a
  number.
  
  Number: For formatting, the number of pattern letters is the
  minimum number of digits, and shorter numbers are zero-padded to
  this amount
  

Problem conclusion

• JDK has been updated to
  
  1)Format year to two digits only when two digit year pattern
  'yy' is mentioned.
  
  2)Format year to four digits when the year pattern string
  contains one, three or four characters.
  
  3)If the year pattern string contains more characters than the
  full year, the year will be zero padded.
