PM70744: EXSLT DATE:DATE-TIME() INCORRECT FOR 30 MIN OFFSET TIMEZONES

APAR status

• Closed as program error.

Error description

• The EXSLT date:date-time() function is incorrect for timezones
  that are offset by 30 minutes, such as India Standard Time
  (IST) GMT+5:30 or Newfoundland Standard Time (NST, Java: CNT)
  GMT-3:30.
  
  The minute part of the timezone offset is calculated as the
  remainder of the total offset divided by the number of
  milliseconds in an hour - which yields a result in
  milliseconds instead of minutes.
  
  This works when the minute offset is 0, but yields 1800000
  when it should be 30, as in the following example:
  
  2012-02-29T11:28:32-03:1800000

Problem conclusion

• The date:date-time() function now calculates the minute part
  of the timezone offset correctly.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.13. Please refer to the Recommended Updates page
