Timestamp incorrect system time

Hello, Guys,
Quick question about system time and timestamp inconsistency.
I used the following program to generate analog output (with duty cycle) but as i am outputting, it give me the time of 12/31/1903 at 16:00.
I checked and reset the system time and it made no difference. please advise,
thank you.

Hello,
The square waveform generator VI that is producing the waveform doesn't use system time as its basis, and that appears to be where the issue lies. By default, the output waveform will be aligned to a t0 (initial time) of 0, since the waveform time stamp in this case is relative to the start of the program. To align the time with the current system time, all you need to do is use the Align Waveform Timestamps VI to shift the t0 value of the generated waveform to match the current time. I've attached an example (aligntimes.vi) built in LabVIEW 7.1.1 that demonstrates - you should be able to adapt it very easily to fit your needs.

Why would Weblogic logs have diff timestamps then system time

How/where can I set the weblogic logfile timestamp to match system time?
The entries in the logs have times that are one hour behind system (Solaris) time
as if not reset for daylight savings time.
Server version is weblogic5.1
Thanks,
-Matt

can you post some sample messages ?
is the server instance using a local file system ?

Incorrect System Time

The mobo is a 875P Neo-FIS2R and the problem is that both in the BIOS and in the OS, the system time is incorrect.
I've tried changing the battery, no good though X(
Don't know what else to do ?( I've never experienced this kind of problem before.
BIOS version 1.6.
Except the above problem, everything else works just great wit this m/b

The clock should tick even without a battary at all, it will simply reset each time you power down.
Since you don't say the bios settings reset each time it's safe to assume the batary is fine and that the RTC is probably dead.
Just to be sure befor you replace the board, remove all the PCI cards, mouse etc... Then clear the CMOS ( disconnect the main power 1'st ).
Just with the minimal hardware and a KB check if the clock is still frozen.
If it is you need to have it replaced.

Comparing incoming file name having timestamp with system time.

Hi,
The scenario is File to FIle.
i have to read the incoming file name which will be having time stamp.
compare the time stamp with the system time .
if the difference in time is within specified time then send the file to target location,else send a mail that file is not placed in target location.
please enlight me on how this scenario can be done.
Thanks,
Akkasali.

if you mean the actual time stamp on the file and not the file name then ref: http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3417300)ID2044216150DB12410233167314983393End?blog=/pub/wlg/15154
else if you mean the time stamp on the file name itself then use dynamic configuration and then read the file name and do the further processing - /people/shabarish.vijayakumar/blog/2009/03/26/dynamic-configuration-vs-variable-substitution--the-ultimate-battle-for-the-file-name

System time is incorrect

I just recently installed Arch Linux i686. I thought I got the time set correctly when I first installed Arch, but now I notice that the system time is incorrect. I live in Tucson, Arizona. Arizona (execpt for the Navajo Indian reservation) is on MST (GMT-7) year round, no DST. I dual boot this machine to both Windows and Linux, so the hardware clock is set to local time. When I boot to Windows, the correct time is displayed. in /etc/rc.conf, I have
HARDWARECLOCK="localtime"
TIMEZONE="Ameria/Phoenix"
When I boot Arch, and type the date command, it displays localtime - 7 hours. Also, if a create a new file and do a "ls -l" command, the timestamp on the file is localtime - 7 hours. It appears that Arch thinks the hardwareclock is set to UTC, even though I have HARDWARECLOCK="localtime" specified.
How can I fix this?
(I did a pacman update a week ago and it looked like it installed a new kernel. Maybe this is when the incorrect system time started. Not sure.)
Charles Bailey

The Arch boot sequence, from the wiki page, http://wiki.archlinux.org/index.php/Boot:
1 Grub or Lilo
2 Kernel and memory management functions loaded into memory
3 init called - follows instructions from /etc/inittab
4 /etc/rc.sysinit is called.
Early in rc.sysint , from my x86-64 Arch on a dual AMD cpu, the realtime-clock driver is loaded. In my case, it's rtc-cmos. Bugs have been reported in various places about this driver. I don't know which version of the driver, or which kernels might be affected. The driver is for PC-style computers; without it ACPI would not function.
Then, the hwclock may be adjusted for system drift depending on use of localtime or UTC.
After the local filesystems are mounted, the hwclock may be adjusted again.
You could add lines to rc.sysinit to echo the hwclock time to the screen for the boot sequence using "/sbin/hwclock -r" to see which adjustment instance is causing the errors and then take steps to correct the adjustment or prevent the adjustment from occurring.
Edited for clarity and typos.

System Time is Incorrect After Waking From Hibernation

If my MBA runs out of battery when its asleep, after coming back to life, the system time is wrong. The time is correct when it comes back from normal sleep.
Message was edited by: DrFooMod2 -- Corrected OS version

Hi
Same here. On PC boards the clock is usually buffered by a small battery.
Maybe there is no battery in the MBA. But the clock is synchronized over the internet by asking a time server. So you dont need to do it manually

The system time is val seconds older than the queue space time

We did a time change on our system to future time and getting the above error after we are trying to reboot the application with current time.
Please help !

The Tuxedo queueing subsystem access to an accurate system time in order to
implement message expiration times and other time-related features. If the
system time is reset to an earlier value, time related queueing features can
work incorrectly. For this reason,
Q_CAT:2238 is logged if such a situation is encountered. Timestamps can be
stored within individual /Q messages as well as in the queuespace
superblock.
If the time change into the future was of short duration, the easiest way to
resolve this problem is simply to wait until the real time reaches the
previously set future time. Once this happens, the queuespace will once
again be usable.
If the queuespace is used on a test system and the data on it is not
valuable, another option is to recreate the queue space from scratch.
Another option is to reset the system time back to the previous future time
in order to use the queuespace.
If this is a production system and you are a BEA support customer, you can
file a support case about this situation. It may be possible for support to
write a utility program to modify the timestamps within the queue to earlier
values or to give you a version of /Q compiled to accept an environment
variable that can be used to modify /Q's idea of the system time.

How can i get the System Time from the other host

I want to get the System Time from the other host in the LAN,How can I get the Time using Java.
Such as I am in WIN 2000 and I have a Unix host in LAN, I want to get unix host System time, How can I do it.

Open a socket to port 13 and read a string with the time.

Open a socket to port 27 and read 4 bytes that are a network order timestamp
Assuming that your UNIX machine has those services running, most do

How to get system time from cRIO?

Hello,
I have an NI cRIO-9076 chassis with an NI-9467 GPS module and an NI-9234 module.
I've downloaded the FPGA Timekeeper application which synchronises the FPGA clock to the 1PPS GPS, this works well. What I want to do is create a trigger that at a pre-defined HH:MMS the system will start to acquire and log data from the Accelerometers connected to the NI-9234 module.
I have added the controls for the entry of the HH:MMS and calculated the time in seconds. I would like to compare the system clock once it is locked to the entered timestamp and then trigger.
As I only have a value that represents seconds in the day I need to calculate the offset from EPOCH to compare against the GPS time reference. I have read that the NI system clock runs from 01/01/1904 instead of the EPOCH 01/01/1970.
The question is how do I get the current system time so that I can compare it against the entered time? I only need seconds in the day = (HH * 3600) + (MM * 60) + (SS)
Thank you,
Kind Regards,
Simon

You should use the Get Date/Time in Seconds VI which will return a timestamp. You can then format this timestamp using the Format Date/Time String to give you exactly the time format that you need. Then you can extract the numbers you need and do your math.

How to get system time format in time stamp

Hello All,
I have one problem regarding Time stamp. I want system time stamp format in Time control. If my system date/time format change then automatically my time stamp format should also change.If my system Time stamp format is hh:mm:ss AM/PM dd/mm/yy so in my LabVIEW time stamp format should also same. If System time stamp format hh:mm:ss AM/PM mm/dd/yyyy so in my LabVIEW time stamp format should also same.
So Please help me its a very important for my automation application.
Thank You.

Hi Vinal,
have you tried the FormatDateTimeString function with a standard string indicator and the "%c" formatcode as described in the help instead of the generic timestamp indicator?

How to compare the current system time with two timing?

want to get the current system time and compare with the two different timing example startwindow time as 2:00:00AM and endWindowTime as 6:00:00AM. if my current system time falls between these window i have to execute my rest of the code.
my below code works for fine for JAVA 1.6 version when i do the same code with JAVA 1.4 i am getting different date and time
String starTime=(String) NightlyvendorStatus[0].getPropertyValue("startTime");
String endTime=(String) NightlyvendorStatus[0].getPropertyValue("endTime");
Date windowStarttime = new SimpleDateFormat("HH:mm:ss").parse(starTime);
Date windowEndtime = new SimpleDateFormat("HH:mm:ss").parse(endTime);
Date systemdate = new Date();
SimpleDateFormat parser = new SimpleDateFormat("HH:mm:ss");
String systemTime=parser.format(systemdate);
Date currentTime = new SimpleDateFormat("HH:mm:ss").parse(systemTime);
if (currentTime.after(windowStarttime) && currentTime.before(windowEndtime)){
--- rest logic here---}
the output from JAVA 1.4 IS Thu Jan 01 02:00:00 GMT 1970 Thu Jan 01 06:00:00 GMT 1970 Thu Jan 01 03:23:00 GMT 1970
HOW TO DO this logic..

Hi,
You can try converting dates into timestamp and compare just like as comparing two integers variables.

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

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?

How to get the system time(hh:mm:ss) in jspx file itself.

Hi I'm using jdeveloper 11.1.1.3.0.
I am having one transient attribute in VO (data type is Timestamp and format is hh:mm:ss) and created the data control. Now I am drag and drop that attribute in one jspx file itself. if i run that page mean i need the current system time as a output. it ll automatically run in the output page(like digital clock - HH:MM:SS). how to implement this one plz help me sir.

Hi john
I got the output using the poll operation in the jspx file. But the mouse pointer is also updated(arrow mark and round alternatively). so how to stop the mouse pointer update.

'Embed system time as timecode' not accurate?

It appears that the "system time" timecodes are not updated on every frame, even when 'Embed system time as timecode' is checked, and 'Frame Interval' is set to 1.
The timecodes routinely latch onto a certain value, so that several timecodes in a row will report the same system time.
To study this behavior, I recorded a video of a computer screen displaying the current time as an epoch timestamp in milliseconds, and, from the recorded .flv file, read back the timecodes from each video frame as well as the timecodes embedded as amf0 'onFI' events as recorded by FMLE.
You may consult the data I collected below:
A graph showing embedded timecodes above video time:
http://adamflorin.com/xfer/adobe/timecodes-ahead-of-video.pdf
The complete data:
http://adamflorin.com/xfer/adobe/fmle-timecode-bug.xls
The FMLE-created video file used:
http://adamflorin.com/xfer/adobe/fmle-output.flv
This data was collected on a 2008 MacBook.
Has anyone else seen behavior like this? I look forward to doing more tests, on different machines and with different settings, but because they're so laborious to compute, I thought I'd reach out first.
Unfortunately this is quite urgent, so I'm afraid I'll have to investigate other technologies. Any help is greatly appreciated, THANKS!

For what it's worth, frame rate appears to be a factor. I see this issue consistently at 30fps, but never at 24fps or 25fps, where the amf0 timecodes are fairly evenly spaced, at about the duration of one frame.
I'm using VP6 at 640x360, a Logitech C910, Mac OS 10.7.3, FMLE 3.2.0.99.32.
This behavior seems pathological to me. Has anyone else seen this?
