Java convert date to EST timezone to respecting DST

I want to get the current date converted to America/Montreal timezone. I'm doing it like this:

Date date = new Date();
TimeZone timeZone = TimeZone.getTimeZone ("America/Montreal");
Calendar cal = new GregorianCalendar(timeZone);
cal.setTime(date);
String whatIWant = "" + cal.get(Calendar.HOUR_OF_DAY) + ':'+ 
                   cal.get(Calendar.MINUTE)+ ':'+ cal.get(Calendar.SECOND);

log.info(whatIWant);

The conversion is just fine but I was wondering how robust this code is. What will happen when in no daylight saving?

That code is fine. Java automatically takes winter time or summer time into account.

You could also do this by using a DateFormat object to convert the date to a string, setting the desired time zone on the DateFormat object:

Date date = new Date();

DateFormat df = new SimpleDateFormat("HH:mm:ss");

// Tell the DateFormat that you want the time in this timezone
df.setTimeZone(TimeZone.getTimeZone("America/Montreal"));

String whatIWant = df.format(date);
