i need convert a date field in UTC to GMT-5, this is my query;
Select
A1.NAME23,
TO_CHAR(A1.TIME_END,'YYYY/MM/DD HH24:MI:SS')TIME_END,
A1.VAR43
From table
i trying this
select to_char(cast(A1.TIME_END at time zone 'GMT-5' as date ),'YYYY/MM/DD HH24:MI:SS') as GMT-5 from table
but dont work
any suggestions
thanks.
If the column is a DATE datatype, then it's simply:
select time_end - 5/24 from table
It must be this one:
A1.TIME_END at time zone '-05:00'

i changed my datefield to timestamp in PGadmin but now all the fields have '2020-04-24 00:00:00'.
But i want that the time of all the fields have the following value '2020-04-24 12:00:00' so instead that all my field values have 00:00:00 they have 12:00:00. How can i fix this?
This works...
update table
set date = date + interval '12 hour';
HIRE_DATE is in a 'DATE' column. The timestamp is local (Los Angeles); I would like to convert it to UTC.
I can't for the life of me fathom why the UTC output is mangled (Last 2 digits of YY is the DD; and vice-versa) -- and the time does not convert to UTC.
HIRE_DATE: 30/04/2019 12:00:00 AM
select from_tz(to_timestamp(HIRE_DATE,'DD-MM-YY HH24:MI:SS'), 'America/Los_Angeles') at time zone 'UTC' from TABLE
OUTPUT: 19/04/2030 12:00:00 AM
If HIRE_DATE is a DATE data type then you don't need TO_TIMESTAMP.
TO_TIMESTAMP is used to convert a string (i.e. VARCHAR2) into a TIMESTAMP value but you have a DATE value.
Just do
select from_tz(CAST(HIRE_DATE AS TIMESTAMP), 'America/Los_Angeles') at time zone 'UTC'
from TABLE
Actually I don't understand why FROM_TZ does not accept DATE values whereas almost any other date/timestamp related function accept either DATE or TIMESTAMP value as input.
Note, the default output display format of this query is defined by current user session NLS_TIMESTAMP_TZ_FORMAT setting. If you are not satisfied with the output format, either change NLS_TIMESTAMP_TZ_FORMAT setting by executing ALTER SESSION SET NLS_TIMESTAMP_TZ_FORMAT = '...' or use TO_CHAR function to set output format explicitly.
Instead of
... AT TIME ZONE 'UTC'
you can also use
SYS_EXTRACT_UTC(...)
The upper returns a TIMESTAMP WITH TIME ZONE value, the second one returns a TIMESTAMP value.
Would this do any good?
SQL> select from_tz(cast (sysdate as timestamp), 'UTC') result from dual;
RESULT
---------------------------------------------------------------------------
27.09.20 10:59:28,000000 UTC
Or, in your case
select from_tz(cast (hire_date as timestamp), 'UTC' from dual
No need to apply any format mask to hire_date as it is a DATE datatype (at least, that's what you said).
You use the word "convert" which can mean one of two things:
change the data type, which is what FROM_TZ does
change the value from one time zone to another, which FROM_TZ does not do.
You didn't give your expected output, so we may misunderstand.
To change the data type:
with data(dte) as (
select date '2019-04-30' + interval '12' hour from dual
)
select from_tz(cast(dte as timestamp), 'America/Los_Angeles') from data
FROM_TZ(CAST(DTEASTIMESTAMP),'AMERICA/LOS_ANGELES')
30-APR-19 12.00.00.000000 PM AMERICA/LOS_ANGELES
To get the simultaneous datetime value in UTC:
with data(dte) as (
select date '2019-04-30' + interval '12' hour from dual
)
select cast(sys_extract_utc(from_tz(cast(dte as timestamp), 'America/Los_Angeles')) as date) from data
CAST(SYS_EXTRACT_UTC(FROM_TZ(CAST(DTEASTIMESTAMP),'AMERICA/LOS_ANGELES'))ASDATE)
2019-04-30 19:00:00
I want to convert type date unix to timestamp in Informix.
My column date1 contains values as 1598915961, 1598911249, 1598911255...
expected output: 2020-02-13 15:00:00
How should I do it, please?
In Informix, you can use dbinfo() and 'utc_to_datetime':
select dbinfo('utc_to_datetime', myepoch)
The idea is that you can add the seconds to the date '1970-01-01'. I don't have Informix on-hand, but the syntax is something like this:
select datetime('1970-01-01') + interval date1 second
I just wanted to know whether the following SQL is good to convert US server time to Thailand date. As we have 12 hours difference in the time, and TH time is ahead of U.S time
SELECT TO_DATE(
TO_CHAR(
SYSTIMESTAMP AT TIME ZONE 'Asia/Bangkok', 'yyyy-mm-dd',
'NLS_DATE_LANGUAGE = american'), 'yyyy-mm-dd') AS TODAY
FROM dual;
It works perfectly fine. But are there any other better way to convert timestamp of server from one timezone to another as I need to compare today's date based on this result in my outer SQL.
You could CAST the timestamp to your desired timezone.
For example,
SQL> WITH data AS (
2 SELECT SYSTIMESTAMP AT TIME ZONE 'Asia/Bangkok' tm_bangkok FROM dual
3 )
4 SELECT tm_bangkok,
5 CAST(tm_bangkok AT TIME ZONE 'EST' AS TIMESTAMP) tm_est
6 FROM data;
TM_BANGKOK TM_EST
--------------------------------------------- ----------------------------
03-NOV-15 12.54.18.951000 PM ASIA/BANGKOK 03-NOV-15 12.54.18.951000 AM
There is no reason to cast a TIMESTAMP to CHAR and then back to TIMESTAMP again. Simply do
SELECT SYSTIMESTAMP AT TIME ZONE 'Asia/Bangkok' AS TODAY
FROM dual;
I need to cast a DATE value in a query to a TIMESTAMP WITH TIME ZONE, but currently I'm getting the TimeZone Region ('Europe / Paris') which is not valid to be used by EF.
For example, when doing this:
select CAST(FECHA AS TIMESTAMP WITH TIME ZONE) from test;
I currently get this output:
07/03/14 09:22:00,000000000 EUROPE/PARIS
But I need it to be like:
07/03/14 09:22:00,000000000 +01:00
Any idea how to accomplish this?
You can cast the DATE to a TIMESTAMP, then use FROM_TZ to convert this timestamp to a timestamp with time zone:
SQL> SELECT from_tz(CAST (SYSDATE AS TIMESTAMP), '+01:00') tz FROM dual;
TZ
-------------------------------------------------
07/03/14 09:47:06,000000 +01:00
With #Vincent Malgrat solution you need to get the TIMEZONE_HOUR and then, format it to use in your query. I don't know if there is any chance to make it automatically.
I can suggest you to nest some functions. It is not the cleanest solution but it works for me
SELECT TO_TIMESTAMP_TZ(TO_CHAR(CAST(FECHAHORA AS TIMESTAMP WITH TIME ZONE), 'DD-MM-YY HH24:MI:SS TZH:TZM'), 'DD-MM-YY HH24:MI:SS TZH:TZM' )FROM TEST;
And the result will be something like
03/03/14 09:58:02,000000000 +01:00
Regards!
Use
ALTER SESSION SET TIME_ZONE = '+01:00';
before your SELECT
