multiple clock for different time zone

[faezsghfi]

how can I have multiple clock? one clock for my country and another one for some one else?
I test this :

Calendar c = Calendar.getInstance();
c.setTimeZone(TimeZone.getTimeZone("GMT+03"));
customAnalogClock.setTime(c);

and this :
customAnalogClock.setTimezone(TimeZone.getTimeZone("GMT+03"));

but none of theme worked
