[xsl] Calling mutator java method (date fields to seconds-since-epoch wi

Hello,

I need to determine the number of seconds past the epoch given the
year, month, day, hour, and minute fields (as strings).

This can be done with the java.util.GregorianCalendar class using the
set(year,month,day,hour,minute) mutator and calling the
getTimeInMillis() accessor. I have been able to demonstrate this in a
sample main class that uses GregorianCalendar:

                        // For year,month,day,hour,min -> seconds since epoch
                        import java.util.Calendar;
                        import java.util.GregorianCalendar;

                        public class MyDate {

                        public static void main(String args[]) {
                                Calendar myCal = new GregorianCalendar();
                                myCal.set(2006,7,21,13,26,0); //1156181207
                                System.out.println(myCal.getTimeInMillis()/1000 
- 1156181207);
                        }

                        }


The following xslt shows how I instantiate a GregorianCalendar. Two
outputs are obtained:
1) A failed attempt to get the seconds-since-the-epoch after the set method call
2) The objects toString, which shows that the date information is
actually the time of execution and not the date set

This leads me to believe that the mutator call did not 'take effect'.
Looking to previous java-interaction solutions that I have created, I
notice that this is the first time I am calling an object's mutator
method, which returns void. Does this need to be handled differently?

Regards,
Tim
