Converting UTC dates to other timezones

Question

I\'m converting a UTC time to another timezone, using this method:

SimpleDateFormat format = new SimpleDateFormat(\"yyyy-MM-dd HH:mm:ss\");
Date parsed = for

You need to take Daylight Savings into consideration. I do this by working out the offset (from UTC) in millieseconds. Something like this should work.

int currentOffsetFromUTC = tz.getRawOffset() + (tz.inDaylightTime(parsed) ? tz.getDSTSavings() : 0);
String result = format.format(parsed.getTime() + currentOffsetFromUTC);

The inDayLightTime(...) method returns a boolean and must be passed a Date object in order for it to decide if that 'date' represents one during a DST period or not.
