calendar.getTime()

[Sully Sylvester]

I am trying to convert a time from one timezone to another


java.text.SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
formatter.setTimeZone();

String formattedDateTime = formatter.format(date);

parseDate(formattedDateTime);

// this all works ok and i get string with correct time in whatever timezone i put in setTimeZone();

private Date parseDate(String dateFormat)
{

Calendar cal = new GregorianCalendar();
cal.set(Calendar.YEAR, substring of dateFormat put to int);
cal.set(Calendar.MONTH, substring of dateFormat put to int);
cal.set(Calendar.DATE, substring of dateFormat put to int);
cal.set(Calendar.HOUR_OF_DAY, substring of dateFormat put to int);
cal.set(Calendar.MINUTE, substring of dateFormat put to int);

return cal.getTime();
}

Ok problem is that cal.getTime returns correct time but wrong timezone so date object returned will have correct time bubt timezone will be GMT so if i change result again to another timeZone it will think its GMT as opposed to its correct timeZone.

Any help appreciated.

Thanks,
Carl

Converting Time Between Time Zones

Thanks for that. unfortunately the result is mapped into a xml file and xsd requires it to be a date object so i have to call getTime or convert calendar at some point to a Date() and this is where i get my problems

Well, Date objects don't have a timezone so the whole concept of "converting from one timezone to another" is misguided if that's what you need. Perhaps your question is really "I have a string that represents a time in timezone X and I want to create a Date object from that"? But it can't be because your code seems to start with a Date object. If that's the case then you don't need to do anything.

You can display that Date object as a string that interprets it in timezone X using a SimpleDateFormat, as you already know.
