FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode, sharing)

SunOS parakeet 5.8 Generic_108528-27 sun4u sparc SUNW,Ultra-60


A DESCRIPTION OF THE PROBLEM :
According to the Javadoc documentation to print the hour part of a date in 12 hour format, you would use %tI.

http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html#dt

'I' Hour for the 12-hour clock, formatted as two digits with a leading zero as necessary, i.e. 01 - 12.

I found that if you print a time that has an hour of 12 PM, it will print 00 instead of 12.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Wed Aug 18 12:00:00 CDT 2004
12:00 PM

ACTUAL -
Wed Aug 18 12:00:00 CDT 2004
00:00 PM


REPRODUCIBILITY :
This bug can be reproduced always.

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

public class Test {
public static void main(String[] args) {
try {
Calendar calendar = new GregorianCalendar(2004, 7, 18, 12, 0, 0);
Date date = calendar.getTime();
System.out.println(date);
System.out.println(String.format("%tI:%tM %tP", date, date, date));
}
catch(Exception e) {
e.printStackTrace();
}
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
You can test for the 12 PM case and just create the string manually with a 12 instead of 00.
