JR62495: USING THE TWDATE SETTIME AND GETTIME JAVASCRIPT APIs CAUSES AN INTEGER OVERFLOW

workflow.20002.delta.repository

APAR status

• Closed as program error.

Error description

• The TWDate.getTime() JavaScript API returns an integer
  representing time in seconds while the TWDate.setTime(int
  timeInSeconds) JavaScript API takes in an integer value
  representing the time in seconds. When you use these APIs
  together and the date exceeds 2038-01-21, an integer overflow
  occurs.

Local fix

• User may use the following scripts as a workaround.
  
  tw.local.date1 = new TWDate("2099-01-21 00:00:00.00.00");
  tw.local.date2 = new TWDate();
  log.info("original date1=" + tw.local.date1 + ", date2=" +
  tw.local.date2);
  
  function copyDate(oldDate) {
  var newDate = new TWDate();
  var year = oldDate.getFullYear();
  var month = oldDate.getMonth();
  var date = oldDate.getDate();
  var hours = oldDate.getHours();
  var min = oldDate.getMinutes();
  var sec = oldDate.getSeconds();
  var ms = oldDate.getMilliseconds();
  var day = oldDate.getDay();
  
  newDate.setFullYear(year)
  newDate.setMonth(month);
  newDate.setDate(date);
  newDate.setHours(hours);
  newDate.setMinutes(min);
  newDate.setSeconds(sec);
  newDate.setMilliseconds(ms);
  newDate.setDay(day);
  
  return newDate;
  }
  
  tw.local.date2 = copyDate(tw.local.date1);
  log.info("date1=" + tw.local.date1 + ", date2=" +
  tw.local.date2);
  

Problem summary

• The Rhino JavaScript runtime engine doesn't support the long
  data type.
  

Problem conclusion

• A fix is available or will be available that introduces new
  JavaScript APIs: TWDate.getTimeString() and
  TWDate.setTimeFromString(String timeString).
  

Temporary fix
