I have code in postgresql transform to sql server
In postgresql while inserting in table with data type timestamp with time zone in UTC format, it inserted with time zone
create table public.testt123 (tz timestamp with time zone)
insert into public.testt123
select now() at time zone 'utc'
select * from public.testt123
enter image description here
I have tried same with Sql server, below query
create table Test1(tz [datetimeoffset](7))
insert into Test1
select GETUTCDATE() AT TIME ZONE 'UTC'
enter image description here
It inserted without time zone, I have check using SYSDATETIMEOFFSET() but it gives time zone with current datetime not UTC
I have tried by left function, but it is correct way?
Select cast(left(SYSDATETIMEOFFSET() AT TIME ZONE 'UTC',28) + DATENAME(TZOFFSET, SYSDATETIMEOFFSET()) as [datetimeoffset](7))
enter image description here
Based on the comments, I suspect what you want is:
SELECT SYSUTCDATETIME() AT TIME ZONE 'UTC' AT TIME ZONE 'India Standard Time';
Though this could be abbreviated to:
SELECT SYSDATETIMEOFFSET() AT TIME ZONE 'India Standard Time';
I have check using SYSDATETIMEOFFSET() but it gives time zone with
current datetime not UTC
Correct, SYSDATETIMEOFFSET() returns a datetimeoffset but with the current UTC offset of the database server. Specify AT TIME ZONE 'UTC' to get a datetimeoffset with the UTC time with a zero offset:
SYSDATETIMEOFFSET() AT TIME ZONE 'UTC'

I am trying to convert from UTC to Eastern Standard Time. But the code below is not producing the result that I expect.
SELECT
GETUTCDATE() AS UTC_Date, --original datetime value
GETUTCDATE() AT TIME ZONE 'Eastern Standard Time' AS ETZ
The result is
UTC_Date = 2022-01-16 01:15:39.920
ETZ =2022-01-16 01:15:39.920 -05:00
How can I get a simple date time with the offset applied instead of just added on to the end of the string?
I'm having this issue
select getDATE() AT TIME ZONE 'utc'
SELECT GETUTCDATE()
output:
2021-06-08 12:50:19.260 +00:00
2021-06-08 11:50:19.260
Why does this happen? Basicaly I want to convert to UTC but it adds one hour.
Current time in Portugal is now 12:50, so the first output should be 12:50
Firstly, to quote AT TIME ZONE (Transact-SQL):
Converts an inputdate to the corresponding datetimeoffset value in the target time zone. When inputdate is provided without offset information, the function applies the offset of the time zone assuming that inputdate is in the target time zone. If inputdate is provided as a datetimeoffset value, then AT TIME ZONE clause converts it into the target time zone using the time zone conversion rules.
GETDATE returns a datetime, it has no offset property. This means, per the quoted text above, it is assumed to be UTC when you set it the the UTC timezone. As you state you are in Portugal then you are currently UTC+1, and this means you (effectively) get a "UTC+1" UTC time.
GETUTCDATE, unsurprisingly, gives you the UTC time, and thus is correct.
If you want a datetimeoffset time with the current UTC time then use sysdatetimeoffset:
SELECT SYSDATETIMEOFFSET() AT TIME ZONE 'UTC';
This query:
select getDATE() AT TIME ZONE 'utc'
has two separate parts:
getDATE()
The documentation says:
Returns the current database system timestamp
AT TIME ZONE 'utc'
The documentation says:
Converts an inputdate to the corresponding datetimeoffset value in the target time zone. When inputdate is provided without offset information, the function applies the offset of the time zone assuming that inputdate is in the target time zone.
So the result from the local time is then double-adjusted again into the time zone offset
GETUTCDATE
This value represents the current UTC time (Coordinated Universal Time).
So if you used this with AT TIME ZONE 'UTC' then you would get the correct time
I have a (Azure) SQL Server database with timestamps in UTC. I want to get the date at a specific timezone.
The following shows the issue
DECLARE #TS DateTime2='2020-02-08 23:00:00'
SELECT CAST((#TS at time zone 'W. Europe Standard Time') as date) as StartDate, #TS as StartTimeStampUTC, #TS at time zone 'W. Europe Standard Time' as StartTimeStampLocalTime
StartTimeStampUTC : 2020-02-08 23:00:00.0000000
StartTimeStampLocalTime : 2020-02-08 23:00:00.0000000 +01:00
StartDate : 2020-02-08
I would have expected the StartDate value to be 2020-02-09, as local time is 2020-02-08 23:00 + 01:00 = 2020-02-09 00:00
How can I get the correct date?
You can follow the below-mentioned process in SQL Server.
1. Get UTC time using - GETUTCDATE()
2. Get difference between your DateTime and UTC DateTime using below link -
https://dzone.com/articles/dates-and-times-in-sql-server-at-time-zone
3. Add that difference in UTC DateTime
Please find below script -
SELECT GETDATE() AS 'Local Timezone',
GETUTCDATE() AS 'Utc_Timezone',
(DATEADD(HOUR,5,DATEADD(MINUTE,30,GETUTCDATE()))) as'Local Timezone based on UTC'
I have added 5:30 Hrs based on my local timeZone.
This seems to do the trick :
SELECT CAST(dateadd(hour,DATEdiff(hour,#TS AT TIME ZONE 'W. Europe Standard Time',#TS ),#TS) as date) as StartDate
answer is now 2020-02-09 as expected
I want to convert UTC value to Eastern Time Zone (any time zone) in SQL directly. I am trying below query but getting DATETIMEOFFSET.
I am trying to convert below UTC DateTime into Eastern time zone.
SELECT CONVERT(DATETIME,'2019-05-27 13:00:00' AT TIME ZONE 'Eastern Standard Time'
I am expecting output for above query is '2019-05-27 09:00:00' but the actual output is coming like '2019-05-27 13:00:00 -04:00'
you can do this
select CONVERT(datetime, SWITCHOFFSET(CONVERT(datetimeoffset, '2019-05-27 13:00:00'), DATEPART(TZOFFSET,
SYSDATETIMEOFFSET() AT TIME ZONE 'Eastern Standard Time')))
You're close. So far, you've told SQL Server the native time zone for the datetime that you've passed in. Now you need to tell it to convert it to something else. This should do the trick:
SELECT CONVERT(DATETIME,'2019-05-27 13:00:00')
AT TIME ZONE 'Eastern Standard Time'
AT TIME ZONE 'UTC';
This should give you something with the -00:00 offset. If you don't want that, cast the result back to a time zone-less datatype.
What is the sql server query to retrieve current time stamp with us/central time zone?
You need both local and remote timezones, so Oracle can calculate the difference e.g.
SELECT FROM_TZ(CAST(sysdate AS TIMESTAMP), 'America/New_York')
AT TIME ZONE 'America/Los_Angeles'
FROM DUAL;
30.10.14 08:45:08,000000000 AMERICA/LOS_ANGELES
and
SELECT FROM_TZ(CAST(sysdate AS TIMESTAMP), 'America/New_York')
AT TIME ZONE 'America/Chicago'
FROM DUAL;
30.10.14 10:46:17,000000000 AMERICA/CHICAGO
You can get the list of timezone names with this:
SELECT tzname, tzabbrev FROM V$TIMEZONE_NAMES;
so you can do this:
SELECT FROM_TZ(CAST(sysdate AS TIMESTAMP), 'America/New_York')
AT TIME ZONE 'US/Central'
FROM DUAL;
assuming you are in New York.
If this is for SQL Server 2008 or above, this will provide the time at a specific timezone offset. I don't know if you can provide a timezone name, and using this method, you'll have to handle daylight savings yourself.
declare #dt datetimeoffset = switchoffset(convert(datetimeoffset, getutcdate()), '-06:00')
select getutcdate() as utc, #dt as [datetimeoffset], cast(#dt as datetime) as [datetime]
Time zone support was added with SQL Server 2016. You can now do this:
SELECT SYSDATETIMEOFFSET() AT TIME ZONE 'Central Standard Time'
Note that the identifier Central Standard Time is the Windows time zone ID for Central Time in US and Canada. It is inclusive of both CST and CDT.
