IC81866: EXSLT DATE:DATE-TIME() INCORRECT FOR 30 MIN OFFSET TIMEZONES

WebSphere Enterprise Service Bus V7.5.1 Fix Pack 1 (7.5.1.1)
Version 7.5.1 Fix Pack 1 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• The EXSLT date:date-time() function is incorrect for timezones
  that are
  offset by 30 min, 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 summary

• The EXSLT date:date-time() function is incorrect for timezones
  that are offset by 30 min, 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.

  it should be 30, as in the following example:
  2012-02-29T11:28:32-03:1800000
  

Problem conclusion

• The code was modified to ensure that the offset is calculated
  in minutes appropriately.
  
  This code fix was targeted to be included in the following fix
  packs:
  
  7.0.0 Fix Pack 5 (v7.0.0.5)
  7.5.1 Fix Pack 1 (v7.5.1.1)
