Help needed in date formating

Question

Hi guys merry Christmas in advance .i was trying to write a code to compare given string with current date .
So i have written a piece of code to set hour minute second millisecond of current date to 0.
It worked fine for minute second millisecond but hour always shows 12.
Here is the code.
Please help
import java.util.*;
public class SampleDate
public static void main(String[] args)
java.util.Date date = new java.util.Date();
//convert current date to cal format and set hour min sec mill to 0
java.util.Calendar cal1=java.util.Calendar.getInstance();
cal1.setTime(date);
cal1.set(java.util.Calendar.HOUR,0);
cal1.set(java.util.Calendar.MINUTE, 0);
cal1.set(java.util.Calendar.SECOND, 0);
cal1.set(java.util.Calendar.MILLISECOND, 0);
//convert from cal to date format
date=cal1.getTime();
System.out.println("Current Date in Date Object: " + date);
}Output:
C:\TIMECOMPARE>java SampleDate
Current Date in Date Object: Thu Dec 24 12:00:00 IST 2009Expected output is :Current Date in Date Object: Thu Dec 24 00:00:00 IST 2009

The HOUR field of the Calendar class represents a 12 hour clock format where 0 indicates 12 noon. Instead use the HOUR_OF_DAY in the code as shown below:
cal1.set(java.util.Calendar.HOUR_OF_DAY,0);
