Timestamp in miliseconds
How can I generate a timestamp in the form of the total miliseconds elapsed since 01/01/1904 00:00:00 ?
You can used Get Date/Time In Seconds vi and then convert the output to DBL you will get the time elapsed in seconds.

Returning/passing Java script variable/value to PL/SQL environment
Hi,
Can someone give me a sample code about how to return a Java script variable to PLSQL environment?
for example, I have a javascript function that returns timestamp in milisecond, I then want to write PLSQL code to call this java script function and save its value in a number-typed plsql variable for further calculation, I dont know how the two scripting language communicate.
Thank you very much
Binh
nullThis is quite simple.
I assume that you are able to define html form side through pl/sql. Suppose your new pl/sql value is v_time then in the procedure that you write include one more statement
htp.p('<Input type=hidden name="v_time" value="">');
and also in the form invocation,
htp.p('<form name=app method=post action="time_handler" onSubmit="return false;">');
and to the end you must be having a submit
to it attach a onClick function that calls
simply our validate function..
eg htp.p('<Input type=submit value="process"
onClick="validate();">');
Include in the head portion
the following script using htp.p procedure
function validate()
app.v_time.value=<calculated value>;
return app.submit();
Hope this helps.

TimeStamp miliseconds control in Labview
the question is about the miliseconds part of timestamp. It seems there is no way to control(write) directly the miliseconds part, also when read there is no ms part in the indicator. What is the structure of the time stamp record?Are there some way to write and read ms part (but without string conversion), as bytestream for example and use/write it as array?
I'm not sure what you're concerned about more, the storage space (TIMESTAMP = 128 bits) or the processing time (conversions).
If it's the storage space, you COULD sacrifice the extra range by typecasting to a cluster of four U32s (no conversion time), extracting #1 and #2 (discarding #0 and #3) and storing those two. That's assuming you can live with the overflow that will happen in the year 2040 or so.
Another trick you might consider is storing ONE timestamp value, and ONE mSec timer as a starting point, then store the mSec Timer (32 bits) with each record. When it's time to display a record, use the record's timer minus the starting timer as an elapsed-mSec value, and add that to the starting timestamp to get an absolute times
tamp for each record.
Be careful with that, though. The timestamp does not have mSec directly - it looks like field #2 is fractions of a second - so you'll have to convert one or the other to add them correctly.

Do you know if we can use the date format in miliseconds with TO_CHAR() function?
Not if you are using a DATE data type. DATE columns do not store sub-second precision. You would have to be using a TIMESTAMP data type to see milliseconds.

Gateway for Sybase or MS SQL - support for Timestamp
Hi All,
Is there any way to get Timestamp data out of Sybase or MS SQL Server?
I thought this would be pretty straightforward, but after a short investigation I'm no longer that optimistic...
The "Database Gateway for Sybase User's Guide" says in Appendix A, that the following conversions are performed by the gateway:
(Sybase - Oracle)
DATE - DATE
DATETIME - DATE
SMALLDATETIME - DATE
TIMESTAMP - RAW
TIME - CHAR(15)
It says the same for MS SQL Server.
What I need is a conversion from Sybase DATETIME into Oracle TIMESTAMP, but I'm guessing there is a limitation of the Gateway
and it is not able to use the millisecond data in any way... Am I right?
Or maybe there is some magic setting in the .ini file for this? Things like HS_NLS_TIMESTAMP_FORMAT seem to be unsupported by Sybase gateway.
I'm using 11.2.0.1 on Linux.
Thanks for any hints.Hi,
As you have seen in the documentation the Sybase and SQL*Server datatime columns are translated as Oracle DATE datatypes, so the milisecond data will be lost.
the 11.2 DG4MSQL Users Guide actually says -
SQL*Server Oracle Comment
DATETIME DATE Fractional parts of a second are truncated
although the Dg4Sybase Users Guide has the same conversion it does not have the comment.
The only way round it would be use a different non-Oracle datatyp from which you could extract the millesecond part of the string.

Higher precision of timestamp when wrinting to txt
Hello,
I would like to have a higher precision (--->miliseconds) of the timestamp when saving waveforms to .txt. Labview only prints the date and the time in HH:MMS. As I am acquiring data with a rate of 1k, 1000 data values have the same time description in the .txt-file.
Note: This problem only occurs when writing to .txt, it is no problem to get a higher precision by using the graph or the chart.
Any help or suggestions would be appreciated.Thanks so far.....
Maybe I was not precise enough. What I am looking for is the opportunity to easily manipulate the format of the timestamp, which comes with my data and then write it to .txt. I already used the "Format Date/Time String"-VI to get the time with the miliseconds part and joined this time information with the data of the waveforms, which I also had to extract from the waveforms before, afterwards, but I thought there would be a more elegant way, because if I can extract the ms-part from the timestamp it must have been in it before, right ? ;-) So why can´t I tell Labview to also display the ms-part, when using the "write waveforms to .txt"-VI? I attached a .txt-file with a short excerpt of data, which should visualise the problem.
Regards

I used Java stored procedure that gets the time in milisecond , it returns milisecond but change in time is about 15 milisecond.

Same procedure works on different server as expected . How can i solve this problem.In fact i need to calculate time execution of party of my application and i need to milisecond accuracy.
First off all I used systimestamp then i got milisecond precision But i reliaze that result is truncated by about 15
Before java procedure I used script below to test precision
declare
currtimestamp timestamp (9);
begin
for i in 1..1000 loop
currtimestamp := systimestamp;
dbms_output.put_line(to_char(currtimestamp,'ff9')) ;
end loop;
end;
example result show what is problem
part of result
358000000
358000000
358000000
358000000
358000000
358000000
358000000
374000000
374000000
374000000
374000000
As seen last 6 digit always zero . I am not care about last 6 digit.
At least after 358000000 out put might be 359000000 not 374000000 -
I am transferring data from table A to table B. there is a column in table A with datatype 'timestamp' that has the fraction seconds in the data. However I am using data type 'date' in table B where I am transferring the timestamp data to. I can query the fraction saconds using the hh:mm:ss.ff in table A but when I use it in table B it shows nothing and errors out.
i tried to use the CAST function to query the fraction seconds in table B but it shows zeroes.
question is - is the fraction second being transferred to table B? what can I do to make sure fractions are being transferred from A to B
any help will be appreciatedHi,
question is - is the fraction second being transferred to table B? what can I do to make sure fractions are being transferred from A to BThat is the one of the difference between TIMESTAMP and DATE. TIMESTAMP holds the miliseconds also. To transfer fraction of second you need to convert B table's datatype to TIMESTAMP.

I would like to keep track some events based on their occur time point. Hence, I use timestamp to record event occurance and need to keep track the closest timestamp to the new timestamp added. However, when I use systimestamp - 1, the experession produce the timestamp of the previous day. Can I control finer timestamp scale of the system or can I use other expression to have the closest timestamp to current timestamp (maybe in seconds or miliseconds) ?
E.g.
Select systimestamp, systimestamp - 1 from dual;
Systimestamp Systimestamp-1

UTC timestamps in milliseconds offset from January 1, 1970
Hello,
The problem is that I must generate miliseconds offset from jan-1-1970 for a java app from my PL/SQL application.
how do I can, from a given datetime, get UTC timestamps in milliseconds offset from January 1, 1970?
I'm in the Canada/Eastern time zone and I'm using the following function:
CREATE OR REPLACE FUNCTION date_to_float (dt IN DATE)
RETURN FLOAT
IS
BEGIN
RETURN 24 * 3600 * 1000 * (NEW_TIME (dt, 'EDT', 'GMT') - TO_DATE ('1970-01-01', 'YYYY-MM-DD'));
END;
so when I use this function to generate events after the november 2nd, the hour isn't accurate on the application side because the static usage of new_time with EDT source timezone.
How can I make this function reliable over time?
ThanksIt looks like you are looking for the unix style epoch time:
This code will give it to you plus allow you to configure the resolution, by default it will return the number of seconds since 1-Jan-1970, but by varying either the scale or precision you can get more or less detail, and you can even change the date epoch date used in the calculation.
create or replace
function date_to_epoch(
p_date timestamp with time zone default systimestamp,
p_scale number default 1,
p_precision number default 0,
epoch timestamp with time zone
default to_timestamp_tz('1970-01-01 utc',
'yyyy-mm-dd tzr')
) return number is
tmp interval day(9) to second;
sec number;
begin
tmp := p_date-epoch;
sec := extract(day from tmp)*24*60*60;
sec := sec + extract(hour from tmp)*60*60;
sec := sec + extract(minute from tmp)*60;
sec := sec + extract(second from tmp);
return trunc(sec*p_scale,p_precision);

hi all,
i need to convert current time to unix timestamp. actaully i'm a PHP programmer but i plan to use jsp in the future. when i write web applications with PHP, i use mktime() function which converts any given time to unix timestamp value. so i store returned integer value to database as an integer field. this helps me when i need to compare dates with sql commands. and when i need to reconvert this integer to date value i use anoher php function date().
so my question is, how can i do such a thing with java? people talk about a class java.sql.Timestamp, is it the timestamp that i look for?
any helps (especially code samples) will be useful...ok i found out how to get the time in miliseconds. by getTime() method of Date class. but i still have problems. if u interested this topic is moved to java programming forum under title "date in miliseconds".

Hi Gurus,
I have column (datatype-timestamp) in physical layer but as when i am checking in user interface found only date is displaying
Any clue regarding to this
thanksHi Gurus,
I viewd the data in the physical layer it shows in date,time,miliseconds
datatype is also timestamp.when i am casting it shows the data but without casting onlyn dates are coming
it shows some gap(blanck space) after the date
thanks

Any suggestions?I looked in the folder from which I want to synch photos, but there is no such thing as an "ipod photo cache" in that folder, or sub-folders, as suggested in the link which you were nice enough to provide.
I have also tried removing photos from my iPad2 Photos App, and "iTunes has stopped working" shows up again as soon as I click on the "Synch photos from" button. -
Changing of the timestamp in sender file adapter in archive mode
Hi,
I have a requirement where in I have to archive a file with timestamp different from that generated by XI.
Please let me know if this can be done and if so how can we handle the changes to be made to the timestamp in the sender adapter in archive mode.
regards,
Srinivas.Srinivas,
Option 1) Create a bat file..to run the perl script you call..
Perl script..
#!/usr/bin/perl -w
print("Starter that you want to change: ");
chomp($badex = <STDIN>);
print("Starter that you want added: ");
chomp($goodex = <STDIN>);
foreach $file (<$badex*>){
@fields = split(/$badex/,$file);
$goodfile = ("$goodex" . "$fields[1]");
rename("$file","$goodfile");
Run that on the os
That should fix it.........
Option 2) On your local Machine create a java file..add this code to it
public class Utils
public static int Randomizer(){
int randomInt = 0;
randomInt = (int) (Math.random()*1000);
return randomInt;
public static void main(String[] args)
Randomizer();
save and compile..
Create a bat file to add the number returned from the random to your targetFilename
so it would be something like..
mv oldFileName Newfilename+randomizer... and also get this command written to a file..helpful later on.........
Hope that helps
