Calendar and time zones

[Rodrigo Tassini]

Dear friends,

I have a swing application, that I need only hour and minute, in the DB it's stored with date, time.

My app do this:

    
String strHoraInicioNormal;
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT-3"));
DateFormat df = new SimpleDateFormat("dd/MM/yyyy H:mm");
if (iHora < 12) {
	calendar.set(Calendar.AM_PM, Calendar.AM);
}else {
	calendar.set(Calendar.AM_PM, Calendar.PM);
}
calendar.set(Calendar.HOUR, iHora);
calendar.set(Calendar.HOUR_OF_DAY, iHora);
calendar.set(Calendar.MINUTE, iMinuto);
System.out.println(calendar.toString());
strHoraInicioNormal = df.format(calendar.getTime());
System.out.println(strHoraInicioNormal);

The output of syso in the code is that:
1)java.util.GregorianCalendar[time=?,areFieldsSet=false,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="GMT-03:00",offset=-10800000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],firstDayOfWeek=2,minimalDaysInFirstWeek=1,ERA=1,YEAR=2010,MONTH=1,WEEK_OF_YEAR=9,WEEK_OF_MONTH=4,DAY_OF_MONTH=26,DAY_OF_YEAR=57,DAY_OF_WEEK=6,DAY_OF_WEEK_IN_MONTH=4,AM_PM=0,HOUR=9,HOUR_OF_DAY=9,MINUTE=0,SECOND=33,MILLISECOND=117,ZONE_OFFSET=-10800000,DST_OFFSET=0]

2)26/02/2010 12:00

Would anyone knows why the output of a String is not 20/02/2010 09:00 ??
(The format date is to Brazil, then the format is dd/MM/yyyy, MM/dd/yyyy like the USA).

What you displayed there used the timezone from the DateFormat (which I can't tell what that is), not the timezone from the Calendar.

[Rodrigo Tassini]

Sorry, I don't understand.
Don't have a Factory method to DateFormat that receive a TimeZone.

[Paul Clapham]

"Factory method"?

I don't know what you mean by that. The DecimalFormat class has a setTimeZone method. You didn't use it.
