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.

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,

Setting System time

How to set system time using java?
When I use VC ++, I can call as.....
char sz[MAX_PATH + 1];
     int len = GetSystemDirectory(sz, MAX_PATH);
     sz[len ++] = '\\';
     sz[len] = '\x0';
     strcpy(sz + len, "timedate.cpl");
     ShellExecute(NULL, "open", "control", sz, "", SW_SHOW);
thus I can set the system time using Day/Time Dialog..
But how can we set the system time in java?
Have a same time dialog for us to use?
Or what is the API or class we can set the system time
directly?

You can use Runtime.exec() to do this in a very similar way. You should not need to worry about getting the system directory since it should be on the path.

How to change system time through java program

Hi
I want to know, how to change system time through java program.
give me a idia with example.
Thanks

There isn't any core Java API for this. Use JNI or call an external process with Runtime.exec().

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.

System time for Java Stack and ABAP Stack of PI

HI,
     We have a scenario in which we have a synchronous flow of data. In the forward flow we have used field UZEIT in an RFC Lookup to register the inbound time and in the reverse flow we have used current time function of SAP PI mapping. PI time is the local time of the server, However UZEIT is 4 hours ahead compared to PI time.
Both the Java and the Abap stack are installed on the same server.
Kindly let us know the reason for the difference in time on both the stacks.
Regards,
            Milan Thaker

Hi,
   Yes I am refering to the System->Status time in ABAP Stack. Could you please tell me where can I check the System time of JAVA stack. I got one XML file in UME which refers to some timestamp in com.sap.security.core.usermanagement but I failed to locate this field. Please let me know where can I find the Java stack time and how can that be synchronized with ABAP.
         Also, is there any time zone settting in JAVA for UTC , the way we have in ABAP

Set system time to myrio programmatically synchrinized with GPS

Hello,
I have succesfully connected the PMOD GPS to my RIO and i extract the time and date string from the NMEA sentence in the following format:
Time: HH:MMS
Date: DD/MM/YY
I would like to synchronize myrio system time to the GPS time. I have tried to use the nisyscfglvlib: Set Time.vi. For test purposes i try to set the time using a time stamp constant like the attached picture. However, when i run this code i get the following error. Where i can find this library and how do i add it to myrio? I
LabVIEW: Failed to load shared library nisyscfg.*:nisyscfg_lv_sysapiPropertySetString:C . Ensure that the library is present on the RT target. Use either MAX to install NI software or FTP to transfer custom libraries to the RT target.
LabVIEW: Failed to load shared library nisyscfg.*:nisyscfg_lv_rmcfgPropertyGetItem:C . Ensure that the library is present on the RT target. Use either MAX to install NI software or FTP to transfer custom libraries to the RT target.
Is there another way to set the time of myrio programmatically?
Thank you,
Christos

Hi ckyamaha,
Below is an example on how to set a real time system's time using the System Configuration API.
https://decibel.ni.com/content/docs/DOC-20082
It sounds like you may need to include the library on your myRIO when you configure it in NI-MAX. If you haven't already installed the System Configuration API, you can do so from this link: https://decibel.ni.com/content/docs/DOC-13216
You can add the library to your myRIO in the Add/Remove Software menu in NI-MAX. Instructions for installing software using NI-MAX can be found here: http://zone.ni.com/reference/en-XX/help/373925A-01/myriohelp/myrio_advanced_config/

Synchronize system time and set system time zone in SAP

Hi,
How to Synchronize system time and set system time zone in any SAP system?

Nabarun -
Setting of the system time may be different depending on your enviroment and systems. (Windows, AIX, etc)
Windows enviroment you can use a time server or net time command, I believe its simialr with UNIX but I do not know that command.
Setting the time zone in SAP is done through the IMG in client 000. You can get there with transaction SPRO.
Once in the IMG, navigate to:
SAP Netweaver
General settings
Time Zones
Maintain Time Zones (here you can define the time zone settings/rules)
Then go to:
SAP Netweaver
General settings
Time Zones
Maintain System Settings
There you can change the time zones for the system.
Hope this helps.

Set system classpath using java program??

Set system time in both unix and NT

i need to write a software to be run on the 2 platforms to set the system time if anyone know how to go about doing it please guide me along and provide me some code.
thanks in advance

You cannot set the system time using pure Java, so I guess you'll have to use JNI or Runtime.exec().
If you use JNI, you'll have to set up a native method and the build a different DLL for each platform. From my point of view this is the cleanest way.
Using exec() requieres to detect the system your program is running on, and then call the appropiate external program or command.

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?

How to set system time from Terminal while booted from 10.6.3 server install disk?

I'm installing from a 10.6.3 server install disc onto a Mac Mini. However, the battery on this Mac Mini is pretty much dead, forcing the system time back to 1/1/2001. Through some research, this has created a problem in that I cannot move beyond the Welcome screen during setup of OS X server. It looks like the binary has issues with the system time being older.
But I'm stuck in that I don't know how to adjust the system time from the Terminal Utility on the boot CD. Can anyone help?

Hey, i just run in to something similar, tonight while trying to fix a computer.
The user set the time and date on his computer to 1998 and computer locked everything including time and date in system preferences, and his user account basicly making him from administrator to guest. he could not almost any program properly that required administrator privilages.
to fix this we used this comand in terminal " sudo date 201703162014 " todays time and date
20:17 03/16 2014
we tryed everything and this fixed in 2 seconds
ps: when you type sudo in terminal it whil give you a warning the improper use of this command is bad.... click continue.otherwhise you will not be able to execute the command.
thanks again for this post and have a great day

TimerThread problem after setting system time

Hi,
We are creating an application where we schedule some jobs in timer thread. Say I have scheduled a job after one hour and in between I have changed the system time. Then timer thread excecutions are not happening properly. While resetting the system time we are restting the JVM time also by Calender.setTime(Date). Please tell me what went wrong in this case.
Thanks in advance,
Champak

Did you check this bug report:
[java.util.Timer.scheduleAtFixedRate() fails if the system time is changed |http://bugs.sun.com/view_bug.do?bug_id=4290274]

This does not reset the jvm time, it sets the time of this calendar instance as described in the javadoc.

Program speeds up System time?

Hi, im writing an animation program in swing that loads and displays images in a seperate thread. there is a variable sleep time in between display times (because of a timestamp on the image).
the wierd thing is that when I output the timestamp to a string after sleeping for the appropriate time per frame, the time seems to be going faster. I thought this was just an internal bug, but when I go to http://www.time.gov/ the applet there shows the time being sped up while my program is running.
Is there a known issue with threads and sleeping that affects the system time? thanks

Huh?
"speeds up system time"? "time seems to be going faster"? Man, if you can make time go faster, let me know, because this Monday has already lasted several weeks.
Seriously, what are you saying? You tell it to sleep for 100 ms but it sleeps less? Or more?
If it's that the time is later than you expect when it wakes up, then that's no surprise, since sleep only guarantees that it will sleep at least that long (unles interrupted). It could sleep longer, depending on the vagaries of your OS's and VM's schedulers.
Or are you saying that after 10 seconds of real wall clock time have passed, your system clock has advanced 12 seconds?

Showing System time using Java Beans

Hi,
Anyone have any source code for writing ajava bean using a text-field to show the current system time which is updated very second at run-time.
Thanks.

Hello.
It sounds to me like you are in the wrong forum. This is for Enterprise JavaBeans, a server side tech, and not the GUI type of JavaBeans. For GUI JavaBeans you should take a look at http://forum.java.sun.com/forum.jsp?forum=39

Mobile Device - Setting System Time/Date class

Hi All,
If I use the java.util.Date class, it returns a different time on the .toString() method than my clock is actually showing... The .toString() returns a time that is 2 hour behind.
Basically, my timezone is GMT+2. So, if my time (displayed on my clock top right corner of my device's screen) is 3:00, the .toString() method returns that it is actually 1:00!
Why could it be 2 hours behind??? Where does the Date class actually get the time from?
tks
Christiaan

You can also use WMI to set the time on remote computers.
(From the Windows PowerShell 2.0 Bible)
$Credential = Get-Credential
foreach ($Server in Get-Content -Path c:\Scripts\Servers.txt)
$TimeObject = @{
Class = "Win32_OperatingSystem"
ComputerName = $Server
Credential = $Credential
EnableAllPrivileges = $true
$CurrentTime = ([wmi]'').ConvertFromDateTime($(Get-Date))
(Get-WmiObject @TimeObject).SetDateTime($CurrentTime)
