Convert xsd:dateTime to UTC

Question

Hello community,
Within a message mapping I have to convert a field containing date, time and timezone to UTC/GMT timezone.
Example:
2008-10-06T01:11:06+02:00 = Incoming value from source field, incl. local time + time zone offset
2008-10-05T23:11:06 = Expected value of target field, incl. UTC date and time
How can I achieve this conversion with an UDF?
Best regards,
Wolfgang

Hi,
U can chabge the time zone of the calender ussing TimeZone java class .
Try this UDF:
Import : java.text.*;
UDF:
AbstractTrace trace = container.getTrace();
String strDate =a;// "2008-10-06T01:11:06+0200";
          Date date=null;
          SimpleDateFormat sdfSource = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
          try{          
               String dt = strDate;          
               date = sdfSource.parse(dt);
               trace.addInfo("NOW1:"+date);
               //Time Zone
               Calendar cal1 = new GregorianCalendar(TimeZone.getTimeZone("GMT+05:30"));
               trace.addInfo("Current Timezone="+cal1.getTimeZone().getDisplayName());
               String timeZoneId = "UTC";//Canada/Central";  // EX.
               trace.addInfo("Getting Time in the timezone="+timeZoneId);
               Calendar mbCal = new GregorianCalendar(TimeZone.getTimeZone(timeZoneId));
               mbCal.setTimeInMillis(date.getTime());
               Calendar cal = Calendar.getInstance();
               cal.set(Calendar.YEAR, mbCal.get(Calendar.YEAR));
               cal.set(Calendar.MONTH, mbCal.get(Calendar.MONTH));
               cal.set(Calendar.DAY_OF_MONTH, mbCal.get(Calendar.DAY_OF_MONTH));
               cal.set(Calendar.HOUR_OF_DAY, mbCal.get(Calendar.HOUR_OF_DAY));
               cal.set(Calendar.MINUTE, mbCal.get(Calendar.MINUTE));
               cal.set(Calendar.SECOND, mbCal.get(Calendar.SECOND));
               cal.set(Calendar.MILLISECOND, mbCal.get(Calendar.MILLISECOND));
               Date newdt =  cal.getTime();
               trace.addInfo("Getting Time in the timezone=####"+newdt);
               SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
               strDate = sdfDestination.format(newdt);
               trace.addInfo("NOW3:"+strDate);
          }catch(ParseException pe){
                trace.addInfo("Parse Exception : " + pe);
return strDate;
