Converting timestamp with timezone to milisecs

Hi guys,
How to converting timestamp with timezone to milisecs?
I'm using oracle 10g.

Regarding timestamp with timezone

Hi,
I have the following timestamp with timezone issue.
From java program I am passing the datetime with timezone value to database (INTERVALTIME (column name)).
PrepareStatemenet statement;
java.util.Date dt = ISODateUtil.parse("2006-06-21T18:00:00+00:00");
SimpleTimeZone zone = new SimpleTimeZone(0,"IST");
Calendar cal = converting the dt to calendar;
cal.setTimeZone(zone);
statement.setTimestamp(col, new Timestamp(cal.getTimeInMillis()),cal);
In database INTERVALTIME (column name) coulmn type is TiMESTAMP WITH TIMEZONE.Database is in PDT (GMT-8) timezone.
Now the problem is :
Even if i send the datetime of IST timezone, it is displaying in PDT (GMT-8) timezone.
How can i resolve this issue?

Oracle ODBC driver and TIMESTAMP with timezone

Does anyone know if it is possible to return data from a "TIMESTAMP WITH TIMEZONE" column using the Oracle ODBC driver and an ADO Recordset?
I am using the Oracle driver version 10.2.0.2 and TIMESTAMP fields work fine.
I can call Recordset->Open() with a query like "SELECT * FROM TABLE" when the table contains a column of type timestamp with timezone but when I execute a statement to see if there are results as in
if (!(srcRecsetPtr->BOF && srcRecsetPtr->EndOfFile))
my application throws an unhandled exception and exits. The exception is not a COM exception and I'm not sure how to get back additional information if that's possible.
The only information I've been able to find in searching TechNet and MetaLink is that a workaround is to wrap the columns in a TO_CHAR or TO_DATE conversion first but that's not a good solution for my problem since I am executing user specified SQL which may join multiple tables.
I've found one other note that says the documentation should be corrected and that these fields are NOT supported period (Bug #4011640).
I've experimented with the Bind Timestamp as Date option in the ODBC connection and with various ALTER SESSION settings to attempt to change the NLS_TIMESTAMP_TZ_FORMAT but I have been unable to get past the problem.
Any ideas are greatly appreciated.
Thanks,
Troy

Hi Justin
Thanks for your help.
I tried what you mentioned and I could connect myself via SQL*Plus without passing a password and a login, Extern authentification seems to work and my user seems to be right configurated.
But he problem goes on via ODBC. When I test connection in the ODBC Data Source Administrator of Windows XP, test fails and seems to forbid connection without userID and password. When I try to connect via ODBC in my program the same problem appears : "Unable to connect SQLSTATE=28000 [Oracle][ODBC][ORA]Ora-01017: Invalid username/password;logon denied" I could not connect in this way.. What's wrong ?

Oracle timestamp with timezone

Does CR support column of type "timestamp with timezone" column. I am getting error message "Failed to retrive data from database. Details:Not implemented". Thanks

Since this is the Crystal Reports Java forum, you need to specify the explicit Java java.sql Type that the Oracle JDBC driver exposes the database type as.
I'm not familiar with that data type, so don't know if it's mapped to the Timestamp type or not.
Note that CR4E 2.0 supports up to JDBC 4.0 types.
Sincerely,
Ted Ueda

Why have I lost the info of timezone (Timestamps with Timezone )

I have been trying to get timestamps with timezones working in my Java application, but I don't seem to get the data I expect back from the JDBC driver
my field type is Timestamps with Timezone ,in the database,I saw the info of (12-DEC-06 01.12.12.123000 PM -06:00),but I don't know How to get it from Java
I've use the Timestamp aa =rs.getTimestamp("FIELDVALUE");but the timezone is lost, what can I do?
thanks

Timestamps are always GMT based (or could be thought of as timezone neutral) so what you should get back is a timestamp representing a GMT equivalent of the time you see that has a 6 hour offset from GMT. In other words, if the time were 1 PM Central Standard you would get a GMT time of 7 PM.
You should then be able to display that time in any time zone you wish using SimpleDateFormat and specifying the time zone you want to display it in. So if you then display it with Central Standard, the 7 PM GMT would then display as 1 PM again. In other words, 7 PM GMT and 1 PM Central Standard are the same timestamp
If you just display the timestamp using a toString(), you will get the time in the default time zone of the JVM..
Whether the driver actually does this correctly with the Oracle database I can't say. I've made several posts in a variety of places complaining that the driver does not work correctly with timestamps but my experience is limited to regular timestamp fields, not the new Oracle type of timestamp with timezone.
Based on my experience, what you are more likely getting back in the 1 PM- 7 PM example is 7 PM in the default timezone of the JVM.
You should look at the getTimestamp with Calendar options to see if they work better for you.
The main thing to keep in mind is that timestamps are really timezone neutral.

Compare 2 'timestamp with timezone' columns

Hi All,
I'm trying to compare 2 'timestamp with timezone' columns,
comparision works fine as long as there is difference of at least seconds between them.
But when the difference between them is in milliseconds, comparison is failing.

Unique or primary key on timestamp with timezone

While researching whether there was a way to avoid ORA-02329, I found the following:

K15>
K15> alter table dumdum

K15> So, at first glance, the alter table statement to change the datatype from DATE to TIMESTAMP seems like a way of fooling Oracle. But the explain plan reveals a different story:

                Cost: 4 Bytes: 1,25 Cardinality: 50 I was only fooling myself. :-0
But I wasn't done with my research:

          Cost: 3 Bytes: 1,25 Cardinality: 50 Why is Oracle so adamant about not allowing a timestamp with time zone in a unique key? And, given their position on the matter, where does their tolerance for a unique index come from?
By the way, if I had a say in it, I would not allow anything that even remotely looks like a date to be part of a primary key, but that's another discussion.
Thanks,

P.S. All this is on Oracle9i Enterprise Edition Release 9.2.0.8.0. Is it different on 10g or 11g?

See if this helps. You can create primary key for TIMESTAMP WITH LOCAL TIME ZONE datatype.
SQL>CREATE TABLE Mytimezone(Localtimezone TIMESTAMP WITH LOCAL TIME ZONE primary key, Location varchar2(20) );
Table created.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/ch4datetime.htm#i1006169
TIMESTAMP WITH LOCAL TIME ZONE Datatype
TIMESTAMP WITH LOCAL TIME ZONE is another variant of TIMESTAMP. It differs from TIMESTAMP WITH TIME ZONE as follows: data stored in the database is normalized to the database time zone, and the time zone offset is not stored as part of the column data. When users retrieve the data, Oracle returns it in the users' local session time zone. The time zone offset is the difference (in hours and minutes) between local time and UTC (Coordinated Universal Time, formerly Greenwich Mean Time).

Php input date/time as timestamp with timezone

This is a nightmare!!!!
I have numerous databases, all of which use timestamp format
date/times, which are easy to echo according to user timezone
preferences using putenv ("TZ=".$_SESSION['MM_UTZ']); and echo
date($_SESSION['MM_UTF'], ($whatever));
The only problem is, I have only used these for stamping
"date created" or "date edited" values using Time()
What I am trying to achieve is:
User 1 in UK enters date and time, using a javascript
datetime picker (which normally enters data into field in Y-m-d
H:i:s) and the php inserts this in timestamp format according to
timezone.
User 2 in US looks at date and time and this is echo'd
according to his timezone.
Sounds simple...
I have managed to get so far with the new DateTime object
which incorporates the user timezone preference ($utz)
$ndttime= new DateTime($timefield, new DateTimeZone($utz));
I can then echo this effectively using
echo $ndttime->format('$utf'); ($utf being user timeformat
preference)
My stupid problem is trying to get the $ndtime into the
database!!!!
I know this sounds ridiculous but I use the DW insert wizard
which only uses values from a form and if I echo $ndtime into a
hidden field, it doesn't process this value in time.
I attach the current insert script.
Is this simple?
Heeeeelp.

This will echo as a date/time object - i.e. Y-m-d H:i:s, but
the $utf variable is a session variable with user time format
preferences, so it could be D, d/m/Y H:i:s or m-d-Y H:i:s
etc.

Comparision of TIMESTAMP with TIMEZONE

Hi,
One of the column columnA is of timestamp datetype i.e value stored in it is '2007-09-20 04:00:00.0'
I am using the following in SQL
select * from tableA
where columnA = TO_TIMESTAMP('2011-05-12 21:00:00','YYYY-MM-DD HH24:MI:SS').
This is always returning null results..
Is the syntax correct? Do I need to change the format to accept milli seconds?
Thanks
-Sree

where columnA = TO_TIMESTAMP('2011-05-12 21:00:00','YYYY-MM-DD HH24:MI:SS').
This is always returning null results..So there is no record with that exact date & time.
Is the syntax correct?yes
Do I need to change the format to accept milli seconds?no

TimeStamp with time zone vs java Date

In the developer's preview release notes, I read about the extended support on Oracle TimeStamp. We are currently planning to migrate current TIMESTAMP columns to TIMESTAMP WITH TIMEZONE to keep the user time zone with the typed date. Here is my question: Which time zone is persisted using a direct to field mapping between a java.util.Date and a TIMESTAMPTZ column? As the java.util.Date contains no time zone (in opposition to java.util.Calendar), does TopLink uses the JVM time zone? WHat is the best to data structure to keep date/time & time zone in our entities? Thanks, Yannick.

I believe it would be the local timezone of the session. If you map a Date to the TIMESTAMP TZ then the SQL written out will not include a TZ value.
Typically if you wish to map to a TIMESTAMPTZ field you would want to use an object in the model that can hold both the Timestamp and TZ values. This is most commonly a Calendar.

Display UTC-Timestamp in timezone of user/server

Hello,
the view of my WD Component displays UTC-Timestamps in a table (Cell Editor LinkToAction).
The user has the possibility to alter the timestamps by providing date and time.
The controller converts date and time to a UTC-timestamp by using ABAP-Statement CONVERT with timezone of server (sy-zonlo).
The timezone is CET (UTC1). Therefore the fields to enter the time is displayed in UTC1 but the timestamp is displayed as UTC. The user might be confused, because when entering a time in the inputfield, the timestamp will be displayed 1 hour in the past.
The domain of the timestamp is TZNTSTMPS. I also tried to convert the timestamp into a field with domain TZNTSTMPSL, but with the same effect.
Is there a possibility to display the timestamp in the timezone of the server (sy-zonlo) or in the timezone of the user?
Thanks in advance
Patrick

Thank you Phil,
I already use both commands.
The user can enter a date and time which is already displayed in his timezone (use of command CONVERT TIMESTAMP ... and later when user saves his settings use of command CONVERT DATE lv_date TIME lv_time ...).
The date and time that user has given should be displayed as a timestamp later(LinkToAction in a table column).
Hope I made the problem clear. The date and time that the user can enter is already displayed in his timezone. It's just about the timestamp which is displayed after user has given date and time. That timestamp should be also displayed in the timezone of the user and not in UTC.
Thanks for your help so far.

XML dateTime type with timezone info.

Has anyone have problem FTPing xml that conforms to a xml schema with dateTime type?
This is the format of standard XML dateTime type:
"2003-12-17T09:30:47-05:00"
I used the Oracle timestamp datatype, but oracle rejected the dateTime of XML with the error message
"ORA-01830: date format picture ends before converting entire input string."
I have altered the database to use timezone information:
// For eastern time zone.
alter DATABASE SET time_zone = 'Etc/GMT-5';
and use the native oracle datatype
"TIMESTAMP WITH TIME ZONE"
but still doesn't work. I also changed the XML time data to "2003-12-17 09:30:47-05:00", still no good.

I tried couple formats, they all seem to need the "T" in between date and time. If I don't have the "T", I get the error message "ORA-01861: literal does not match format string"
If I use the following input I get the error message
"ORA-31041: Property CreateDate: Memory type (180) not compatible with database type (121)"
"2003-12-11T21:30:47.0"
"2003-12-11T21:30:47.000000"
"2003-12-11T21:30:47.000000000"
"2003-12-11T21:30:47000000"
"2003-12-11T21:30:470000"
If I use the following I get error message "ORA-01830: date format picture ends before converting entire input string"
"2003-12-11T21:30:470000-04:00"
"2003-12-11T21:30:47.000000-05:00"
"2003-12-11T21:30:47.0-05:00"
It leads me to think that "2003-12-11T21:30:47.000000"
is the picture(mask) used by the database. But it has extra "T" in it, and oracle doesn't understand the datatype. Maybe there are two validation going on? one from schema and another during insertion to database? Schema requires "T", but database doesn't understand "T"?
Am I in the right track?
Do you know how do I query the mask used?
Thanks,

More trouble with timezones when storing value in TS WITH LTZ

Using Oracle 9i, JDK 1.4.2.
I have a script using the Jakarta Jelly framework to initialize my db. When I run the script, I want to set the current time in several "TIMESTAMP WITH LOCAL TIME ZONE" columns.
Before the time change, the following excerpt from my script was working fine.
<j:new className="java.util.Date" var="now" />
<j:new className="java.text.SimpleDateFormat" var="format">
<j:arg type="java.lang.String" value="dd-MMM-yyyy hh.mm.ss.SS a Z"/>
</j:new>
<j:set var="ts"
value="cast(cast('${format.format(now)}' as timestamp with time zone) as timestamp with local time zone)"/>
The "Z" in the date/time format produces a 3-letter timezone abbreviation, like "PST" or "PDT".
Before the time change, I was getting "PST" from this, and the code was working fine. When the time change hit, I discovered that Oracle doesn't grok "PDT" (I found info on the internet about this, but I can't find it right now). I thought for a short time on this, and I changed "Z" to "z", which results in "-0700" instead of "PDT". This appeared to work fine. It didn't fail, at least.
However, what I discovered today is that Oracle gets confused by it. It recognizes that as a timezone offset, but it only "half" understands this. When I view the value in SQLDeveloper, it shows a time value 7 hours before the current time, instead of the correct current time as it used to.
I also tried hardcoding a date string, using "US/Pacific", and Oracle groks that, but of course, it doesn't know to use daylight savings time.

that makes sense because you are setting the sessionAttribute at the wrong time.. see you are passing the paramater from index to shop, so you really need to set the sessionAttribute in the index page so it is always available in the shop page.
hope that helps...you will always have this problem when refreshing because when you refresh the value from "customer" is not being passed again.....

Partitioning on a table on the field TIMESTAMP WITH TIME ZONE

Hi I have a very large size table which has grown to a size that we are not able to query it efficiently. We have decided to partition the table. But the issue is the table has a TIMESTAMP WITH TIME ZONE field and not DATE. I have found some links on the web which state this might cause an error. I am planning to create a temp table with the partition rules and at the same time copy data from the original one.
using CREATE TABLE XYZ PARTITION BY RANGE (ABC) ( ---- Partition rules ------) NOLOGGING AS SELECT * FROM XYZ_ACTUAL where 1 = 2;
Then if it works fine, I would rename the table with partitions to the actual name.
Should all this be fine?
The database is very critical. Hence the dilemma.

Have you tried converting the timestamp with time zone to a character string as a partition key, possibly using an edit mask to control the timestamp components used?
Your plan sounds OK to me - if you can get the partitioned table created - but I would test in a development first o see where the lLw of Unintended Consequences might decide to manifest itself.

Compare Date with Timezone

Hi,
I have a Date which is stored in the Database with the timezone like GMT, I have a java.util.Date which is selected in my UI from a Customized Calendar, I am converting this Date with timezone and want to compare this date with the date with timezone stored in the DB? How to accomplish this, please shed some light into this?
Thanks.

I think you need to clarify what you mean by "I am converting this Date with timezone", because it doesn't make much sense to me.
BTW: If the date in your database is a standard SQL Date, then it will be converted to a java.sql.Date when you read it into Java with JDBC. And java.sql.Date is directly comparable with java.util.Date (in fact, it's a subclass).
