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.

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.

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

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,

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.

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.

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)

Any help gratefully recieved.

I wish you luck at running a weblogic application attaching to a database that is 8 time zones away. BST is GMT +1 and PDT is GMT-7 I hope you have plenty of bandwidth. I'd say at least the latency of the connection would be an issue.
Regardless, time zones are based on hours apart. Your time difference is off by more than just "whole hours"? Its also not 8 hours difference. Its almost 11 hours. Also, the date output of you host says 2012. Surely that is mistake?

System Time Zone

Hello Guys,
I m getting an error in tcode st0s "No RFC : No Data Available" in Last Minut's Load. As per SAP reply i have to set system time zone.
Anybody know how to set system time zone.
Pl give me detail steps.
Thanks,
Danniel

Danniel,
The previous response was for the server or client time zone. If you in fact need to set the SAP appliation time zone, that is in SPRO.
Transaction SPRO --> SAP Reference IMG --> SAP NetWeaver --> General Settings --> Time Zones --> Maintain System Settings
You then need to make sure the affected users have their time zones set correctly in SU01.

[SOLVED] System time is +4hrs from hardware clock

Hello again.
Now I can't set up my system`s time properly. (Set system time from hardware clock)
Timezone is GMT+4 (Europe/Samara) and hardware clock (RTC) is set to proper time so does UTC.
But system`s time itself is 4 hours in the future from HW clock!
# hwclock --hctosys --utc
does nothing.
# timedatectl set-local-rtc 1
or
# timedatectl set-time "$mytime"
both do nothing and output following error:
Failed to issue method call: The name org.freedesktop.PolicyKit1 was not provided by any .service files
Also, removing /etc/adjtime does nothing!
How can I fix it?

ewaller,
hwclock from util-linux 2.22.1
Using /dev interface to clock.
Last drift adjustment done at 1353744432 seconds after 1969
Last calibration done at 1353744432 seconds after 1969
Hardware clock is on UTC time
Assuming hardware clock is kept in UTC time.
Waiting for clock tick...

Timer problems on Linux changing system time and data

On Linux SO,
both with flash player plugin and standalone flash player, setting system time with command:
date -s 11:11:11
hang timers (flash.utils.Timer) immediately!

I notice that updating system time (both with "date -s hh:mm:ss" and through ntpd) with a new time in the future doesn't hang up flash.utils.Timer component.
Contrary, if I update system time with a past new one, flash.utils.Timer stops work immediately!!!
This is huge problem for those interfaces that need to run for a long time and also need to be time updated (for examplem through ntp daemon).
Can anyone help me?
PS: Windows Flashplayer doesn't have this problem !!

You can use the call library function node. Once you drop it on your block diagram double click it and you will be able to select the dllyou want to use. Choose kernel32.dll and you will see methods listed called getsystemtime and setsystemtime. Use those

RE6500 system time not set and, why set a DNS address?

How do I set the RE6500 system time to current day if it's showing January 1970? It is connected to the router on both frequencies and the extender output is working on both frequencies. I have set the RE6500 to a static address of 192.168.1.3 as the router address is 192.168.1.1. In the RE6500 the default gateway is set to the router address of 192.168.1.1. Is it necessary to set the DNS address in the RE6500 as the router is the default gateway?

Hi Chadster766; thanks for the prompt reply. I tried using the external primary DNS address set in the router - saving and rebooting - and when that didn't work, I used the same IP address as the router 192.168.1.1. That didn't work either; I did a warm re-boot of the computer after setting the DNS in the RE6500. What am I missing or, should I reinstall the RE6500 and use the default DNS settings? I'm using Windows 7 Sp1 and the RE6500 icon does not appear in Network, so it appears to be an issue between Windows and the RE6500.
