Hi all,

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss z");
java.util.Date date = new java.util.Date();
System.out.println(dateFormat.format(date));

I having this piece of code and the output is

2006-05-11 02:54:00 GMT

My location is GMT +8. So i would need to add in another 8 hrs to the
time.

How can i do it such that the piece of code would always offset the
time correctly?

Appreciate any help

SimpleDateFormat extends DateFormat, so it inherits a method called
setTimeZone. That does what you want, if I understand you well.

While calling setTimeZone will provide the result, it might be better to
use a Calendar, or perhaps a GregorianCalendar. This should
automatically contain a date/time with time zone info included.
SimpleDateFormat inherits the setCalendar method, too, and calling that
will give it the information included in a new Date object but include
TZ data as well.
