A DESCRIPTION OF THE PROBLEM :
Java determinates incorrect time zone in Asia/Irkutsk. Java supposes that it is Asia/Ulaanbaatar. Asia/Irkutsk use winter/summer time, Asia/Ulaanbaatar not.  So, System.out.println(Calendar.getInstance().getTime()); prints wrong time when there is a summer time in Asia/Irkutsk. It prints one hour earlier time.
For example, it prints Sat May 07 09:53:12 ULAT 2005 when time is 10:53.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set computer locale GMT+8, Ulaanbaatar/Irkutsk, use summer time; and date, when summer time is used, for example now (7th May) in Windows Control Panel. Execute System.out.println(Calendar.getInstance().getTime()); . It will print wrong time.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Valid system time.
ACTUAL -
Wrong system time.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.Calendar;

public class Test {

	public static void main(String[] args) {
		System.out.println(Calendar.getInstance().getTime());
	}
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Set time zone to Asia/Irkutsk manually on program start. But it is not a good solution.
