How to subtract time from dateTime in xquery?

How to subtract time from dateTime in xquery??
In ALDSP i tried to use the function xf:add-days but it is showing an error saying invalid function name. I think this namespace is not valid for ALDSP. Is there is any way to add this function in ALDSP???

xquery functions and operators documentation is here :
http://www.w3.org/TR/xpath-functions/
It sounds like you want to ..
op:subtract-dayTimeDuration-from-dateTime
this is not an xquery function that you can call, it is an xquery operation defined by the specification
I believe you can simply use the '-' operator to use that operation.
<newDateTime>
{ $myDateTime - $myTime }
</newDateTime>

How to subtract Time from Sysdate

Hello,
I want to subtract time from sysdate and get the sysdate with time.
Example : = (Sysdate with time)03-mar-2002 16:40:55 - 8 (hours). The result should be like :03-mar-2002 08:40:55
How to write a query for this?.
Please let me know as soon as possible.
Thanks,
Ravi.

Hi Ravi...
SYSDATE includes time, TRUNC(SYSDATE) does not include time.
If you subtract these two, you'll get a positive number of 1.00 or less which is the fraction of a day. For instance high noon would have a fraction of 0.50000. 12:01 p.m. would be 0.50000 + (1/(24*60)), or 0.50069444....
If you want to set the clock back, by calculating a "date" that is 8 hours less than the SYSDATE, then SYSDATE - (8/24) will do that. This will work even if SYSDATE was something like 2 a.m., because it will then set it to 6 p.m. of the day before the day in SYSDATE.
If you want to set a "date" to a specific time on the day of SYSDATE, then calculate the fraction for that time and add it to the TRUNC(SYSDATE). High noon would be TRUNC(SYSDATE) + 0.5.
SELECT TO_CHAR(TRUNC(SYSDATE)+0.5,'DD-MON-YY HH:MI:SS am') AS NOON FROM DUAL;Hope this helps...

SUBTRACT TIME FROM DATE & TIME

Hi.
I need FM which will SUBTRACT TIME from DATE & TIME.
Example:
Date = 05.05.2007
Time = 05:00:00
Time_subtract = 48:00:00
Return of FM:
Date = 03.05.2007
Time = 05:00:00
Do you know any FM?
Thanks!

How to get Time from Different Work Station on the Network

Hi,
How do I get time from different work station on the network using its ip:port etc.
Lets say, my main server-side Java application is running on a work station 123.12.123.1:1527,
the client-side applications are accessing it using above IP.
what I wanna do is, use the time of 123.12.123.1 machine throughout the application, not client local time.
Appreciated..

Ok, this network service on IP:Port is working for me, I hope this is the best way of doing it.
In server application, I have this

How 2 prevent time from changing on leopard and vista?

if i maintain successive boots into the same OS on my macbook, the time is shown correctly, whereas on booting into another OS changes the time. how to prevent this from happening?
Neerav

From what my brother says says about his set-up (he boots into 64 bit Vista periodically), apparently you can't. My understanding is that the two systems do a different version of time at boot, Vista uses a GMT setting in bios, and I think Mac use a local time in EFI. Anyway, the result is several hours difference between the two. I don't use Boot Camp, but I would think if you are on a network with Internet access, you should be able to have the clock reset automatically using System Prefs->Date and Time, and check the box at the top to automatically set the time from the Apple time server.

How to use time from external source as signature time?

Hi,
I have a PubSec based acrobat X plugin for signature creation and verification. So far i knew that acrobat was using my local system time to get signing time and saved that time in the signature dictionary. Now i have to get the signing time from an NTP server, which is different from my local system time, and I want to put this time in the signingTime (M) of the Signature dictioniary. But so far i am unable to modify the (M) dictionary value.
Can you please guide me to achieve this goal?
thanks

thanks for your prompt reply.
actually, using timestamps is not an option. Machine time can be changed and my requirement is to use NTP time during signing and set this time as signing time in the signature dictionary. I have tried adding the time in M dictionary in SigGetSigProperties() and SigGetSigValue() callbacks, but it has no effect.
My question is, is it possible to use time other, than machine time, as signing time in a signature (in signature dictionary) ?
If yes, then can i achieve this, a hint or a point in the right direction can suffice.
if no, then is this limitation part of the new plugin framework? because as far as i remember, it was allowed in digsig plugins.
Finally, can i achieve my goal in an unorthodox way?
thanks

How to prevent timer from repeats

hello there i've made a countdown timer
and i want it when it finishes counting till 0 not repeating from the beginning but do some action
i uesd the method
timer.setRepeats(false);but it stops the timer from counting
i'm using javax.swing.timer;

   SimpleDateFormat timef = new SimpleDateFormat("HH:mm:ss",Locale.getDefault());
   long startT,stopT;
   Date date=new Date();
   public Timer1() {
      super("Timer");
      timef.setTimeZone(TimeZone.getTimeZone("GMT"));
      addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent ev) {
            dispose();
            System.exit(0);
      setBounds(10,10,400,200);
      getContentPane().setLayout(null);
      start.setBounds(10,30,100,24);

      combo.addItem("3 Hours ");
      combo.addItem("4 Hours");
      combo.addItem("5 Hours");
      combo.addItem("6 Hours");
       combo.addItem("7 Hours");
      combo.setSelectedIndex(0);
      start.addActionListener(new ActionListener() {
         public void actionPerformed( ActionEvent e ) {
            try {
                 startT=(combo.getSelectedIndex()+1)*60*60*1000; // change if combo box values changed
            catch (Throwable fe) {
               startT=0;
            startT+=System.currentTimeMillis();
            timer.start();
      stop.addActionListener(new ActionListener() {
         public void actionPerformed( ActionEvent e ) {
            timer.stop();
      clear.addActionListener(new ActionListener() {
         public void actionPerformed( ActionEvent e ) {
            time.setText("");
      time.setBounds(150,30,100,24);
      time.setOpaque(true);
      time.setBackground(Color.pink);
      getContentPane().add(stop);
      getContentPane().add(start);
      getContentPane().add(time);
      getContentPane().add(combo);
      getContentPane().add(clear);
      timer = new javax.swing.Timer(1000, new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            stopT = System.currentTimeMillis();
            time.setText(timef.format(new Date(startT-stopT)));

   public static void main (String[] args) {
      UIManager.put("Label.font" ,new Font("Times New Roman",0,23));
      UIManager.put("Button.font",new Font("Arial",1,21));
      new Timer1();
}

simply the user chooses a time from the combobox say
1 hour
and then hits the start button so the timer begins to
countdown.
my problem here is i want when the countdown timer
reaches 0 hour 0 minute 0 second the frame exit (or
any action)not repeating the default time .
got it?Ah, yes, now I understand. So when the user chooses an interval, 1 hour in this case, you calculate the number of seconds that make up that interval. (Doesn't have to be seconds, depends on the granularity of the choices) Then you count down that many seconds like I described before. Each time the timer ticks, decrement the counter, and also convert the number of second left back into hours, minues, seconds and display that.
So the counter becomes the data model that everything's based on, and you format it for display each tick.
startTimer() {
int interval = // get the interval selected from the combobox
int seconds = // convert interval to seconds
start timer with 1 second period
actionPerformed() {
   seconds--;
   if (seconds == 0) {
      stop timer
      do whatever we were waiting for
   else {
       convert seconds to HH:MM:SS format and display in gui
}

How convert date/time from xml in xdp(Designer)?

Hi, i want to convert date/time format from xml in Designer, date/time value in xml is NOT in common format YYYY-MM-DD (if is in a common format i can do this with pattern)
I have a "DateTime" Field in Xdp can get from Xml date and time:
In XML <DateTime>DD-MM-YYYY</DateTime> i want to convert in XDP in DateTime Field in "DD-April-YYYY"
Can i do this?

You can do this way..
Bind the date field to your XML tag.
Set the display pattern for the date field.
In the initialize event of the date field place the following code.
Set JavaScript as language.
var dtStr = this.rawValue;
var pos1=dtStr.indexOf("-");
var pos2=dtStr.indexOf("-",pos1+1);
var strMonth=dtStr.substring(0,pos1);
var strDay=dtStr.substring(pos1+1,pos2);
var strYear=dtStr.substring(pos2+1);
//Assign the formatted value to the Date field.
this.rawValue = strYear + "-" + strMonth + "-" + strDay;
Thanks

How to convert time from (hh:mm:ss) to (hhmmss) in CSV file

Hi Experts,
I have a CSV file where there is time column which displays time like hh:mm:ss
But the input I should give for loading the data is hhmmss
The amount of records that I have is more than 2 lakhs. I tried many ways to convert the time but I'm unsuccessful.
Can anyone tell me how do I convert the format please.
Thanks

Hi,
You can create a custom infoobject length 6 (say mytime) to read the data from csv file.
In the field routine assign the 6 character length info object to the required time IO(system time) with routine.
Inside the field routine...
result = source_fields-mytime.
The system will take care of conversion as per the user master setting.
Thanks,
Jugal.

How to continue timer from prevous state?

Hi guys,
I have some question regarding on the timer. I doing a project called car washing system. Basically every selection will have limited function.
Example: $2 wash: Heavy Wash (10 sec) -> Air Dry (15 sec )-> Exit
Example: $5 wash: Main Wash (10sec) -> Soap(10sec) -> Heavy Wash (10sec) -> Air Dry (15 sec) -> Exit
So for every state the timer run until it reach the timing, the timer will pause and next state the timer will continue. I'm using toggle switch so when i toggle up the timer, it will start running until it reach the stage and pause for next toggle switch up to continue. But currently there is some error which i toggle up the timer get reset.

You may also want to post questions over on the Certification forum.
http://forums.ni.com/t5/Certification/bd-p/Certification
I'd also recommend checking out the elapsed timer express VI. It doesn't have a pause/resume feature but it doesn't take much to add it. I started from the express VI and just added this functionality.

How to subtract dateTime - dateTime

Does anyone has idea how to subtract in OracleBPEL dateTime - dateTime to get duration? I know only extension function for substracting dateTime - duration (function xp20:subtract-dayTimeDuration-from-dateTime() )

You have to create your own Xpath function for it. Have a look to this example <ORAHOME>\integration\orabpel\samples\references\CustomXPathFunction
