EDT/EST timezones in TIMESTAMP

Hi guys,
This is very urgent.....Help please.
In 9i DB, I need to capture date and timestamp with EDT or EST time zone specifiers. For testing pursposes, I wrote the following code and the result is as:
SET SERVEROUT ON
DECLARE
v_date TIMESTAMP WITH LOCAL TIME ZONE;
BEGIN
v_date := TIMESTAMP '2003-06-15 12:16:30 US/Eastern EDT';
DBMS_OUTPUT.PUT_LINE(v_date);
END;
I get the following result:
15-JUN-03 12.16.30.000000 PM
Actually I need 15-JUN-03 12.16.30.000000 PM EDT or EST depending on the daylight times in the Eastern coast. Also, I did change my SESSION with ALTER SESSION SET TIME_ZONE='US/Eastern' but still I do not get the promising output. I just put it to the forum in the hope if someone could help me out with the new timestamp datatype in this case please.
Any help will highly be appreciated.
Thanks

Odds are the problem is with dbms_output.put_line, not with your timestamp.
Try converting your timestamp back to a string before passing it to dbms_output.

How to Convert GMT in EST timezone

We are comunicating with a system,which send date and time in this format - GMT Date and time in YYYYMMDDHHMISS where HH is 24 hour format.Our server has EST (US) time zone. Now I have to validate if the received time stamp from our client is with in +/- 5 minutes, we need to allow him to do some operation.So How can I compare the time stamps in GMT and EST.Which java classes I need to use to accomplish it, any code snippet wil be hepful
thanks in advance

Try this it may help you.
          Date date = new Date();
         DateFormat estFormat = new SimpleDateFormat();
         DateFormat gmtFormat = new SimpleDateFormat();
         TimeZone gmtTime = TimeZone.getTimeZone("GMT");
         TimeZone estTime = TimeZone.getTimeZone("EST");
         estFormat.setTimeZone(gmtTime);
         gmtFormat.setTimeZone(estTime);
         System.out.println("GMT Time: " + estFormat.format(date));
         System.out.println("EST Time: " + gmtFormat.format(date));Result::
GMT Time: 10/5/05 5:37 AM

Conversion of MilliSeconds to Timestamp

Hi,
I'm using Oracle 10g. I want to convert a millisecond value to its corresponding Timestamp. For a millisecond value of 1093853934771 I get the corresponding unix timestamp as 2004-08-30 04:18:54 in mysql using the function FROM_UNIXTIME.
I tried the following in oracle: Adding the milliseconds to the epoch value of 1970-01-01 00:00:00. But got an error.
SQL> select to_timestamp('1970-01-01 00:00:00', 'yyyy-dd-mm hh24:mi:ss') - (1093853934771/1000) SECONDS from dual;
select to_timestamp('1970-01-01 00:00:00', 'yyyy-dd-mm hh24:mi:ss') - (1093853934771/1000) SECONDS from dual
ERROR at line 1:
ORA-01841: (full) year must be between -4713 and +9999, and not be 0
Can anyone tell me how to solve this? How will I get the same value of timestamp in Oracle also?

select to_timestamp('1970-01-01 00:00:00', 'yyyy-dd-mm hh24:mi:ss') + (1093853934771/1000/86400) from dual;
TO_TIMESTAMP('19

Specific time in different timezones

Hello all,
I have the following scenario. My developement pc is in a PDT timezone and my server is in a EDT timezone. Plus, the date entries in the server need to be GMT values.
I know that, right now at least, there are 3 hours of difference between PDT and EDT, and 4 hours of difference between EDT and GMT.
        Calendar calendar = Calendar.getInstance();
        SimpleDateFormat timeDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss, z");
        Date date = calendar.getTime();
        System.out.println("server:\t" + timeDateFormat.format(date));
        timeDateFormat.setTimeZone(TimeZone.getTimeZone("EST5EDT"));
        System.out.println("local:\t" + timeDateFormat.format(date));
        timeDateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
        System.out.println("GMT:\t" + timeDateFormat.format(date));output:
server:     2007-11-02 11:15:43, PDT
local:     2007-11-02 14:15:43, EDT
GMT:     2007-11-02 18:15:43, GMT
Now, I need to convert today's midnight time (EDT) to GMT from my pc having PDT timezone.
        SimpleDateFormat timeDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss, z");
        String today = "2007-11-02 00:00:00, EST5EDT";
        Date date = timeDateFormat.parse(today);
        System.out.println("server:\t" + timeDateFormat.format(date));
        timeDateFormat.setTimeZone(TimeZone.getTimeZone("PST8PDT"));
        System.out.println("local:\t" + timeDateFormat.format(date));
        timeDateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
        System.out.println("GMT\t" + timeDateFormat.format(date));output:
server:     2007-11-02 00:00:00, EST
local:     2007-11-01 22:00:00, PDT
GMT:     2007-11-02 05:00:00, GMT
1. Why does it show EST instead of EST5EDT or just EDT?
2. Why there are now 2 hours of difference between EDT (EST) and PDT? I think it's related to 1.
I'm pulling my hair out of my head with this one. I'd really appreciate any comments on this. Thanks

Today Nov 5th, my code is working fine. My problem is obviously related to the daylight saving time. Since I seem to be using a recent Java Platform (1.5.0_11), does this mean that DST are not fully supported by SimpleDateFormat?As far as I know, Java 1.5.0_11 supports the TZ rules in the U.S. as they exist now. It's possible that there's a bug in that support. It may also be that Java is using your OS's notion of TZs and your OS may not be up to date. I forget the exact rules as to when Java uses its own TZ rules vs. those of the OS.

Oracle Timestamp Issue

I'm using a Oracle 9.2 database and Oracle 9 JDBC drivers.
The server has its time zone set to GMT and I'm testing from a client in EST.
It seems like the Timestamp are not being returned correctly.
What I think is happening here is mismatch between the time zone of Oracle server and the client that is not being accounted for when the driver is creating timestamps.
If I add the row using sysdate at 8 AM EST on a server running on GMT, then retrieve the timestamp with JDBC using a Java default time zone of EST, I get a timestamp that matches 1 PM EST or 6 PM GMT.
If I retrieve it with JDBC after setting my Java default time zone to GMT (so it matches the server), then I get a timestamp that matches 8 AM EST or 1 PM GMT which is correct.
My hunch is that the driver is just doing a new Calendar and setting the hour directly from the server. So if the server passes 1 PM (or hour 13 in 24 hour day), it just sets it using the default time zone whatever it is. As long as the client default time zone and the Oracle server time zone are the same, everything works fine. If they are different, there will be a discrepancy of the number hours offset between the time zone of the client and the time zone of the server.
Does any one else have any ideas?

First, I am not setting the timestamp without
conversion (#2). The driver is setting the timestamp
and you are suggesting exactly what I think the
driver is doing.
As I understand it, timestamp has NO timezone. It is,
in fact, a long number of milliseconds since Jan 1,
1970 GMT.
Timezones come into play when we go to render the
milliseconds in a way that makes sense ot humans.
In other words, the timestamp for 8 AM EST and 1 PM
GMT are the same. If you don't believe it, create two
Calendar objects, one with EST timezone and the other
with GMT. Set the GMT one to 1 PM and the other one
to 8 AM (same day, year, minutes, and milliseconds).
Then display the time as a long. It is the same value.Correct.

Changing timezone in ISE 1.1.2

Hi,
I need to change the timezone of two ISE 1.1.2 servers. One primary and one secondary. Both are set to "EST" timezone and i would like to change
them to AMERICA/Montreal because they are now one hour late since day light saving change.
According to the release notes, it is not recommended to change the timezone on ISE after the installation. I'm thinking of doing a backup
of the ISE application (in the maintenance GUI or CLI) and then changing the timezone on both servers. After the change the ISE servers will gain one hour. So after i will do a restore of the backup i did just before the timezone change. The timestamp of the backups will be older then the current time
of the servers.
Will this work? Is it the best way to change the timezone?
Does anyone run into this issue? How did you fix that? Did you have any problems?
Thanks in advance.
Stephane

Ive had success with no obvious issues changing time zone on a PSN box. I first broke the join from the PAN server and then did a time zone change. Then rejoin the PSN back to the PAN. Again, I didnt see any issues.
As for the PAN time zone change, I would probably rebuild the box if you didnt feel comfortable. In most cases if you are very fimilar with ISE it take like 30 minutes to put the config back on it ..

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?
Thanks

It 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);

Timezone in Java Date

Hi,
Our application takes the system Date along with current time in PST/MST/CST timezone & serializes the same & send to webmethods. Webmethods sends the serialized object to JMS queue on weblogic server (This weblogic server is in EST). We have a MDB running on weblogic server which gets the message from JMS queue. When I print the Date/Time from this, I get the date/time in EST timezone. Same is inserted in my DB. I want to preserve the value what is coming from webmethods. I guess, my weblogic server is running in EST, it is putting the default time zone of this JVM.
E.g: My application in CST/PST/MST timezone sends the date as 7/18/2006 8.00:00 AM CST to webmethods. In MDB ( which is in EST) , i see the date a 7/18/2006 9.00:00 AM EST
Can anybody tell me how can I preserve the timezone when date moves across timezone.
TIA
Ashish

Perhaps u did not get my point. As the time captured
in CST gets converted to EST, when the user sees the
same over web application, he sees the time in EST,
which is misleading.
If someone punchIn for daily job at 8.00am CST, he
would not like to see timecard from 9.00am EST.You do not get the point yet. You are trying to solve this in a backwards fashion. Keep the time stored exactly as it is. Then adjust the display (with the timezone) based on the users settings.
So when the user in CST looks at it they see CST when an EST looks at it they see EST. But store it all with the one. Storage and display are two different things and you need to grasp this very important point.

Time field - timezone

Hi developers,
in my WDJ, I am calling a webservice which, executed from wsnavigator, returns this time value:
1970-01-01T08:30:47.000Z
On WDJ table I get: 10.30 both with direct binding and computed field such as:
DateFormat df = DateFormat.getTimeInstance(DateFormat.MEDIUM, Locale.getDefault());
return df.format(element.getTimeSent());
The locale the app is in (both from browser and from webdynpro console) is Italy (GMT +1)
So I should see 09.30
Can anyone please help?
Thanks, regards
Vincenzo

Hi,
i recommend to use TimeZone class of java for conversion.
Below is the example :
// Suppose this is a date and time in the EST timezone
String value = "2006-11-28 09:45:12";
DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
df1.setTimeZone(TimeZone.getTimeZone("EST"));
// Parses the value and assumes it represents a date and time in the EST timezone
Date d = df1.parse(value);
DateFormat df2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
df2.setTimeZone(TimeZone.getTimeZone("GMT-1:00"));
// Formats the date in the GMT-1:00 timezone
System.out.println(df2.format(d));
hope it helps.
Thanks & Regards,

EST - Support Daylight Savings Time or not?

We have found an issue with Daylight Savings Time, the "EST" timezone and Solaris. In Java, the "EST" timezone is flagged as supporting Daylight Savings Time. In Solaris, "EST" does NOT support Daylight Savings Time. The Solaris setting is based on the zoneinfo files that come from ftp://elsie.nci.nih.gov/pub/ (presumably an "official" US Government source). In the "northamerica" file, "EST" is equated to "America/Indianapolis" which is the part of Indiana that does NOT support Daylight Savings Time.
So, it would appear that Java supporting DST for "EST" would be a bug but I haven't been able to find any other references to this issue. Anyone have any insight on this?
Mark

I believe the following example will be of some help.
java.util.TimeZone zone;
java.util.Calendar gcal;
java.text.SimpleDateFormat form = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm z");
gcal=new java.util.GregorianCalendar(2004,(4-1),4,14,30);// with default timezone
long t0=gcal.getTimeInMillis();
zone = TimeZone.getTimeZone("America/New_York");// New_York
System.out.println(zone.getID());
form.setTimeZone(zone);
gcal.setTimeInMillis(t0);
System.out.println(form.format(gcal.getTime()));
zone = TimeZone.getTimeZone("America/Indianapolis");// Indianapolis
System.out.println(zone.getID());
form.setTimeZone(zone);
gcal.setTimeInMillis(t0);
System.out.println(form.format(gcal.getTime()));

Date not changing based on timezone during insert into database...

I have a bpel project that gets data in GMT and insert into a database that's based on EST timezone...for some reason during insert into database, I expect it to reflect the time in EST time, but it's not doing so. It's a standard oracle bpel project and there was no customization to the date input. The following are the details:
input data:
<InvoiceDate>
<GLogDate>20110613213249</GLogDate>
<TZId>UTC</TZId>
<TZOffset>+00:00</TZOffset>
</InvoiceDate>
date I get after transformation:
<ns5:invoiceDate> 2011-06-13T21:32:49 </ns5:invoiceDate>
date that gets inserted into the database:
6/13/2011 9:32:49 PM
Any thoughts as to what's going on? Is this the intended fuctionality or how does it adjust itself to the daylight saving? I thought database itself would handle it in this case.
Thanks,
Amkay

WpgMom --
From your description, it sounds totally like you are using Manually Scheduled tasks, which is not what you should be using in your project. If you look at the Gantt bars in the Gantt Chart view of your project, if the Gantt bars are a turquoise color,
you are using Manually Scheduled tasks, and that would be the reason that the dates do not automatically calculate for you. If this is the case, click the Select All button to select every task in the project. In the Tasks section of your Task
ribbon, click the Auto Schedule button. From this point forward, your project schedule will automatically recalculate every time you make any kind of schedule edit.
Also, in the lower left corner of the Microsoft Project application window, you will probably see a button that says New Tasks: Manually Scheduled. Click this button and select the Auto Scheduled option.
To avoid all of these problems in all future projects, click File > Options. In the Project Options dialog, click the Schedule tab. In the Scheduling Options for This Project section, click the pick list where you see the name of your project
and select the All New Projects item on the pick list. Click the New Tasks Created pick list and select the Auto Scheduled option. Click the OK button.
Hope this helps.

Setting the proper timezone.

Hi,
I have a 5th generation Video iPod, and am having problems setting the proper timezone.
If I open the world clock, and pick Halifax, it does not show an accurate time.
My timezone is Atlantic Standard Time (AST), which is the timezone for Nova Scotia, PEI, and New Brunswick Canada. I cannot find AST in the timezone settings choices however.
AST is 1 hour ahead of the EST timezone.
Does anyone know how I can set my iPod to be in the correct timezone?
Thanks,
Shannon

Shannon,
Pick the clock for the city you want. Make sure that is the only clock.
Now go to Settings-->Date and Time-->Set Time Zone. Pick your Time Zone. Now go to Set Clock and set your clock to the correct time. See if it works properly.
