How to change system time from Java

Could someone tell me if there is possibility to change the system time, from within a Java program. And how to do it.

In general, no.
You could do it using JNI if you're running your JVM
with sufficient system privileges.
It seems a highly questionable thing to want to do.
Why do you have a requirement for this?
Sylvia.Now there's an idea (thread now has a 'watch'), I think I'll drop the the idea of being a hacker and learn how to write viruses instead - happy days ahead ...

Thanks in advance

I don't know how to access the registry
by using java code. You can't, without using a native interface (JNI type) library.
This is one, there are others, do a Google search:

Can i change system time using java

hi guys can i change system time using java iam doing one app in that i have to change the system time (my os is windowsXP) please tell me how to change the time

What does this have to do with Swing?
Well, there is no Java API that I'm aware of.
However you can execute any Windows command by using the Runtime class. So you should be able to invoke the Time command.
Search the Java Programming forum. There are plenty of examples on using the Runtime.exec(...) command.

is there any java class available to do this ? or any one having sample code for this?
Your friend Zoe

Hi,
There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
The output of this command can be read using java program....
we can use java exec for executing this system32 vbs script.
use the below program and pass the command "eventquery"
plz refer cscript,wscript
import java.io.*;
public class CmdExec {
public static void main(String argv[]) {
try {
String line;
Process p = Runtime.getRuntime().exec("Command");
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
input.close();
catch (Exception err) {

This sample program will list all the system log information....

42HL833B - How to change system time for Australia

I have a Toshiba 42HL833B that I brought back with me to Australia from the UK.
Everything works OK other than the system time still indicates UK time.
Australia does not come up as a Country option in setup so I have chosen "Other".
There does not appear to be anywhere where you can change the time.
Is it possible to change the time manually somehow?

I dont know if you have users manuals with you but you can download it from here .
Maybe you can find info how to do this.

How to execute system command from java program

Hi all,
I want to change directory path and then execute bash and other unix commands from a java program. When I execute them separately, it's working. Even in different try-catch block it's working but when I try to incorporate both of them in same try-catch block, I am not able to execute the commands. The change directory command works but it won't show me the effects of the bash and other commands.
Suggestions??

The code I am using is....
try
String str="cd D:\\Test";
Process p=Runtime.getRuntime().exec("cmd /c cd
"+str);your str string is already having cd in it but again you ar giving cd as part of this command also please check this,i will suggest you to remove cd from str
Process p1=Runtime.getRuntime().exec("cmd /c mkdir
"+str+"\\test_folder");you should say mkdir once you change your path,but here you are saying mkdir first and then cd D:\Test(this is because of str)..please check this
Process p2=Runtime.getRuntime().exec("cmd /c bash");
Process p3=Runtime.getRuntime().exec("cmd /c echo
himanshu>name.txt");
catch(IOException e)
System.err.println("Error on exec() method");
e.printStackTrace();

How to change system time w/o affecting iCal

When I travel to another time zone with my laptop I would like to be able to change the system time that appears in the menu bar to the local correct time. However, I do NOT want this to cause any changes in my calendar times. I use Calendar only for my home appointments so do not want those to change. Is this possible? Thanks!

Hey bobio,
Thanks for the question. If I understand correctly, you want to change your time on the computer but not the time on the Calendar. I would recommend that you read this article, it may be able to help the issue.
You can change the computer time and follow this to view Calendar events in your normal time.
Calendar: View all your events in a different time zone
By default, Calendar events are displayed in your computer’s current time zone (set in Date & Time preferences).
Thanks for using Apple Support Communities.
Have a good one,
Mario

Program to Set System Time in Java

Is there any way to set the system time through Java. If there is can you help me some information.
Regards,
Shivakumar Thota

Hey Hey,
You could run Runtime.exec() to execute a command such as VBScipt to do it.
Other than that you may have to take a look at Java Native Interface(JNI) that will basically take control of doing anything you need.
Also, You may want to post this in "New To Java" or some other forum other than Java Web Start. You'll get more people to help ya.
Hope this helped,
