I have DB with timezone +04:00 (Europe/Moscow) and need to convert a string in format YYYY-MM-DD"T"HH24:MI:SSTZH:TZM to DATE data type in Oracle 11g.

In other words, I have a string 2013-11-08T10:11:31+02:00 and I want to convert it to DATE data type (in local DB timezone +04:00 (Europe/Moscow)).

For string 2013-11-08T10:11:31+02:00 my desired transformation should return DATE data type with date 2013-11-08 12:11:31 (i.e. with local timezone transformation of time to +04:00 (Europe/Moscow)). Timezone of string may be different and +02:00 in string above is just example.

I tried to do this with TIMESTAMP data type, but no success with time zone transformation.

to_timestamp_tz() function with at time zone clause can be used to convert your string literal to a value of timestamp with time zone data type:

SQL> with t1(tm) as(
  2    select '2013-11-08T10:11:31+02:00' from dual
  3  )
  4  select to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
  5           at time zone '+4:00'         as this_way
  6       , to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
  7           at time zone 'Europe/Moscow' as or_this_way
  8    from t1
  9  /

Result:

THIS_WAY                            OR_THIS_WAY
----------------------------------------------------------------------------
2013-11-08 12.11.31 PM +04:00       2013-11-08 12.11.31 PM EUROPE/MOSCOW

And then, we use cast() function to produce a value of date data type:

with t1(tm) as(
  select '2013-11-08T10:11:31+02:00' from dual
)
select cast(to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM') 
         at time zone '+4:00' as date)   as this_way  
     , cast(to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM') 
         at time zone 'Europe/Moscow' as date) as or_this_way
  from t1

This_Way             Or_This_Way 
------------------------------------------
2013-11-08 12:11:31  2013-11-08 12:11:31

Insert the same date and time as a TIMESTAMP WITH TIME ZONE literal. Oracle converts it to a TIMESTAMP value, which means that the time zone information  Summary: in this tutorial, you will learn how to use the Oracle TIMESTAMP WITH TIME ZONE data type to store date and time data that includes time zones. The TIMESTAMP WITH TIME ZONE data type stores both time stamp and time zone data. The time zone data can be time zone offset e.g., -07:00 which is a difference between local time and UTC time

SELECT
CAST((FROM_TZ(CAST(timezonefield AS TIMESTAMP),'GMT') AT TIME ZONE 'CET') AS DATE) 
FROM table;

Converts a timestamp in GMT to date in Central European time

TO_TIMESTAMP_TZ converts char of CHAR , VARCHAR2 , NCHAR , or char must be in the default format of the TIMESTAMP WITH TIME ZONE datatype. purpose in this function as in the TO_CHAR function for date conversion. Examples. The following example converts a character string to a value of TIMESTAMP  You can use this query, without having to worry about timezone changes. select to_char(cast(application_recv_date as timestamp) at time zone 'US/Eastern', 'MON dd, YYYY' ) from application;

if you want your timestamp with timezone to convert to a date in sync with "sysdate" then use the following:

select CAST(to_timestamp_tz('2013-11-08T10:11:31-02:00',
'yyyy-mm-dd"T"hh24:mi:sstzh:tzm') at time zone to_char(systimestamp,
'tzh:tzm') AS DATE)
from dual

There is a datatype TIMESTAMP WITH TIMEZONE that does that. This converts a date into GMT -- you get the p_locale numbers from the ID column of the  The important thing is, that a timestamp with time zone, which uses actual time zone (not just an offset) is actually more precise, that a timestamp with time zone, where there's just offset. You can get the offset from both, you can't get the full time zone (region) when just having the offset. – Hilarion Jan 31 at 10:51

to cast time stamp to date :

cast(registrationmaster.Stamp5DateTime as date) >= '05-05-2018' AND cast(registrationmaster.Stamp5DateTime as date) <= '05-05-2018'

Convert TIMESTAMP with Timezone to DATE in Oracle. In this oracle tutorial we will learn how Convert TIMESTAMP with Timezone to DATE in Oracle pl/sql. insert into TEST_TIMESTAMP_TIMEZONE (CREATION_TIMESTAMP_TIMEZONE) values (TO_TIMESTAMP_TZ('2015/12/22 10:30:00.000 ASIA/CALCUTTA, 'YYYY/MM/DD HH:MI:SS. FF TZR')); In Oracle9i release 1 (9.0) and up -- yes. There is a datatype TIMESTAMP WITH TIMEZONE that does that. Before that -- no, the Oracle DATE datatype cannot store that, nor is it timezone aware.

I want to convert a timestamp with timezone to a date and retain the time. Cast eliminates the time. Is there another function? Oracle performs all timestamp arithmetic in UTC time. For TIMESTAMP WITH LOCAL TIME ZONE data, Oracle converts the datetime value from the database time zone to UTC and converts back to the database time zone after performing the arithmetic. For TIMESTAMP WITH TIME ZONE data, the datetime value is always in UTC, so no conversion is necessary.

This tutorial introduces you to the Oracle TIMESTAMP WITH TIME ZONE data type By default, the date format for TIMESTAMP WITH TIME ZONE data type is Oracle converted the character string to the corresponding TIMESTAMP WITH​  Oracle Database automatically converts character values that are in the default date format into date values when they are used in date expressions. If you specify a date value without a time component, then the default time is midnight. If you specify a date value without a date, then the default date is the first day of the current month.

Introduction; DATE; TIMESTAMP; Converting Between Timestamps and Dates function, but returns the current date-time within the sessions time zone. TO_TIMESTAMP_TZ converts char of CHAR, VARCHAR2, NCHAR, or NVARCHAR2 datatype to a value of TIMESTAMP WITH TIME ZONE datatype. This function does not convert character strings to TIMESTAMP WITH LOCAL TIME ZONE. To do this, use a CAST function, as shown in CAST. The optional fmt specifies the format of char. If you omit fmt, then char must be in

Comments
  • Except for situations that need 'local' times (ie, scheduling/planning, especially for timezones with daylight savings), it's usually best to store absolute timestamps stored in UTC (and translate on display/report). What are these timestamps being used for?
  • I receive date in this timestamp format from external system and do not know why external system uses them. :(
  • Found my answer.. but in case if you want to double check that timestamp is true or false, I found a good site for this. onlinetimestampconvert.com
  • Thank you! select CAST(to_timestamp_tz('2013-11-08T10:11:31+02:00', 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM') at time zone DBTIMEZONE AS DATE) from dual will be correct way for me
