Hi All,
Oracle version is 10.2.0.3
In my DB many tables with data date type column. But it has EST TIME ZONE DATA, but the customer what to change the EST time data to GMT.
I have used new_time function but it is not working for daylight saving data .
Please put your valuable thoughts to resolve this issue.

Hi Lukasz,
Thanks for your help.
It works well to covert the TIME ZONE. But it couldn’t take care of the DST.

Converting EST to GMT

I am looking for a foolproof way to convert EST to GMT using Java APIs.
I believe GMT is not daylight sensitive and hence, we cannot dependent on a constant difference all through out the year.
Here's what I got in my mind.
TimeZone.setDefault(TimeZone.getTimeZone("EST"));
Calendar calendar = Calendar.getInstance();
calendar.setTime(currentDate); //Timestamp of current EST
GregorianCalendar gmtCal = new GregorianCalendar();
TimeZone.setDefault("GMT");
gmtCal.setTime(calendar.getTime());
gmtCal.setTimeZone(TimeZone.getTimeZone("GMT"));
//now gmtCal has current GMT time inspite of daylight changes in EST.Is this correct?
Thanks in advance.

TZ only really matters when you're converting between String and Date, so use SimpleDate format. (It's in beanshell, but you can put it almost straight into java.) bsh % import java.util.Date;
bsh % import java.text.DateFormat;
bsh % Date date = new Date();
bsh % df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
<java.text.SimpleDateFormat@8d55ee0f>
bsh % df.format(date);
<Monday, March 27, 2006 8:33:28 AM PST>
bsh % df.setTimeZone(TimeZone.getTimeZone("GMT"));
bsh % df.format(date);

EST to GMT/UTC

I need to convert a field called CALL_TIMSTAMP from Eastern Standard Time to MM/DD/YYYY HH24:MM:SS in GMT or UTC.
I was wondering if there is a snippet of code out there, perhaps with a case statement, which identifies whether or not the date is of the current/past year's daylight savings time and takes that into account when pulling the data.

HELP - How to Convert Date in GMT to Local time in Applet

Hi All
Is there a way to convert a date from GMT format into a local time say IST in my Java applet, this GMT date is coming from a postgresql database.
Thanks in advance
Swaraj

Try this with your customization:
java.text.SimpleDateFormat format0 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
java.text.SimpleDateFormat format1 = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
java.util.Calendar cal0 = Calendar.getInstance(new SimpleTimeZone(0, "GMT"));
java.util.Calendar cal1 = Calendar.getInstance(new SimpleTimeZone((int)(5.5*60*60*1000), "IST"));
format0.setCalendar(cal0);
format1.setCalendar(cal1);
java.util.Date date = format0.parse("2003-01-25 00:15:30");
java.lang.String formatted = format1.format(date);
System.out.println(formatted);

Query to Convert EST/PST//MST.. to IST

Hi,
I have a requirement where in i need to capture the task assigned by any client (located in US/UK) to our local DBA team and schedule the task and alert the DBA resource to attend the task at local timezone..
Hence I need to convert the timezone(EST/PST..) to IST
I tried new_time() function,but it doesn't support IST timezone..
Kindly suggest any other solution which is appropriate
Thanks

Well I have to take care of both EST/EDT ,PST/PDT,CST/CDT and there are many clients across with different timezone,hence it has to be a consolidated Functionality

ICal GMT bug

I prefer to use google calendar at work, since iCal does not work on Government Networks. But I like having iCal for its printing capabilities. Solution... I create everything in google calendar and I have it sync to my iCal. Problem:
iCal changes all my events originally created in google calendar to GMT time, so everything is about 5 hours off. I searched the web for answers and got nothing other then alot of unresolved complaints. I tried switching my google calendar timezones around to different countries and re-importing everything into the iCal, but this did not work. So I tried the opposite by changing my iCal timezone to different countries, then deleted and re-imported my google calendar. No dice. I even selected and deselected Timezone support in the settings of iCal, and repeated the early process.
If you guys could fix this issue, it would be greatly appreciated and probably save my life! If its not fixed my loyalties to apple will get swaded by google and windows.

This is a relatively new issue for me on my phone which I've had for well over a year, so I agree that this is an iOS operating issue (I am on iOS 8.1.2).
I found something that works (for me). All of my iCalendar appointments sync through gmail. The issue has been that on my iphone, the appointments can be seen as EST (my time zone) and GMT is visible if I click on the event to view all the details. If I go to edit it, the time changes to GMT. Since I'm never quite sure of the difference between EST and GMT, it makes it tough to change an appointment to the correct time (if the appointment needs to be edited).
After searching around on forums, I couldn't find a relevant answer. The ONLY thing that I do to fix it for me was go to settings on my phone, go to the iCloud section, Share location, and click it on. Ever since then, the GMT has disappeared from my calendar.
My other settings which may or may not be relevant: 1) On iCloud setting, I have Calendars turned off (I use google calendar, so why share with iCloud?); 2) I have Time Zone override (in Calendars section) turned off.
I have no idea what will happen when I travel to another time zone, but I am happy for now!

Time conversion to GMT +8

Dear All,
I am receiving the date and time in this format 310310153323 that is the date is 31/03/10 and time is 15:33:23 so how can I convert this into GMT +8 which can also handle the increment on the date accordingly? Thank you.

newbie14 wrote:
The string is representing GTM+0 so I want to covert it into GMT+8? Any idea please? Thank you.Expanding on reply #1.
1. Create a SimpleDateFormat using a timezone of UTC.
2. Parse your string using 1. The output of that is a Date
3. Create a SimpleDateFormat using a timezone of UTC+8
4. Format an output string using 3 and the Date from 2.
Other than that make sure that you undestand a Date ALWAYS has has a UTC value. Timezone only matters when you parse a String or format to produce a String.

Time/Date to GMT keeping in mind DST

I have a servlet that gets the system Time/Date and needs to convert it to GMT(Greenwich Mean Time), it also needs to convert for DST(Daylight Savings Time) in the code. Any help would be greatly appreciated.

Presumably the current time zone of the client is not GMT/UMT.
So you need to create a TimeZone for GMT/UMT.
Then you use that when creating SimpleDateFormat. Then the format method of that instance will produce a string with the correct (relative) time value.

DST prob for conversion from US/Eastern- GMT but not from GMT- US/Eastern.

Hi folks,
I'm running the following SQL against a Oracle 10.2.0.1 g server using Oracle SqlDeveloper 1.5.3 & then again using SQLPlus 10.2.0.1.0.
I'm attempting to provide SQL that highlights the jump forward by one hour at 2am US/Eastern on 14th Mar 2010.
In order to do this I've converted times from GMT into US/Eastern using the oracle function from_tz and to_timestamp.
The following sql statements are suffixed with a 'correct' or 'incorrect' as to whether they correlate to what I would expect and indeed to the time returned from the World Clock website.
=======================

select from_tz(to_timestamp('14-MAR-2010 0200' , 'DD-MON-YYYY HH24MI'), 'US/Eastern') at time zone 'GMT' from dual; -- returns 14-MAR-10 07:00:00.000000000 US/EASTERN incorrect
select from_tz(to_timestamp('14-MAR-2010 0300' , 'DD-MON-YYYY HH24MI'), 'US/Eastern') at time zone 'GMT' from dual; -- returns 14-MAR-10 08:00:00.000000000 US/EASTERN incorrect

which is as I would expect. At 6:59am GMT the time in US/Eastern is 1:59 am, however, at 7:00am the time in US/Eastern is now 3:00am. This correlates to the times I get back when I perform the same calculations using the converter at the WorldClock.
http://www.timeanddate.com/worldclock/converter.html
However when I attempt to perform the same conversions except in reverse i.e. from US/Eastern to GMT I get different results.
-- everything is fine up until the actual time of the change over (2am US/Eastern). With the 2:00am time though I would expect Oracle or perhaps even the SqlDeveloper client to indicate either of the following :-
a) the time 14-MAR-10 02:00am US/Eastern is actually a non-existant time as per the WorldClock.
b) that it's defaulting the time 14-MAR-10 02:00am to 14-MAR-10 03:00am US/Eastern
instead the results proceeding the sql statements are output and for any time on/after 2am they are 1 hour behind their correct GMT times as per the world clock.
I understand that there is a patch for timezone's from 10.2.0.1 to 10.2.0.4 that should address this, however, the reason I'm posting this is because when I run the above SQL in sqlplus against the same server I get different results except this time both conversions are incorrect.

so it's as if the Oracle Client SqlDeveloper somehow intervenes as the results come back from the server an adjusts it for the first set of conversions but not the second.
Basically it looks like I need the patch for the timezones for 10.2.0.1 but what about the Clients? Is there patches I then need for them? Would the SqlPlus client that ships with 10.2.0.4 return the correct results or once the patch is applied to the server.
Has anyone else encountered this problem and if so would they be able to point me in the direction of a resource describing and resolving it?
Thanks,
Mark.

Hey Robert,
Yes indeed we are paying for Oracle support? As far as I know I logged in through metalink in an effort to investigate this problem.
Our DBA upgraded from 10.2.0.4 to 10.2.0.1 and all the inconsistency went away thankfully.
Thanks for taking the time to reply to me,
Mark.

Convertir un fichier texte UNICODE en ANSI

Bonjour,
Je vous explique ma problématique.
J'ai une application qui me fournit un fichier txt. Lorsque je l'ouvre avec mon vi je le vois a peu près correctement mais il y certain charactères bizzares qui apparaissent. Deplus il me crée des espaces entre les lignes et c'est impossible de travailler dessus avec les fonction labview.
Pour remedier à cela, je suis obligé de l'ouvrir avec le bloc note et de l'enregistrer en le passant au format ANSI.
Une fois cette action faite, tous deviens normale et je peux faire fonctionner mon VI.
Ma question est:
Est il possible de le faire en automatique car j'ai beaucoup de fichier à traiter.
Je vous met en fichier joint un example de fichier .txt que j'ai en sortie de mon application,
il n'a qu'une ligne mais si vous l'importez avec Labview, vous verrez que dans la premiere case du tableau il y a un charactère bizzare et que labview creer 2 lignes supplémentaire vide.
Si vous faite la manipulation de sauvegarde au format ANSI avec le bloc note tous devient normale
Merci de votre aidre car je suis un peu coincé et mon application Labview n'à plus lieu d'être si cette convertion n'est pas faite en automatique.
Cordialement,
Résolu !

Si tu veux tester. C'est une méthode... bien particulière, voir expérimentale. Pour étudier le code Unicode to ANSCII, j'ai modifié un vi du site de NI. Je transforme l’Unicode en ANSCII, en ne gardant qu'un U8 sur 2. Les 2 premiers U8 définissant que le fichier est Unicode 255 puis 254. En ne gardant qu'un U8 sur 2, si le deuxième est >0, alors c'est un caractère spéciale, donc je le supprime. Convertir est… terminé.
