We are currently doing an upgrade on Oracle source, because of which all the date time field timezone will change to UTC.
Currently, we have SSIS packages in place for moving data from Oracle to SQL Server Database.
Is there any way we could have a shortcut to change the dates to local timzezone before moving them in our database in SQL Server? Rather than updating each Package/Procedure to include the timezone change. If its a date field coming up, change the timezone from UTC to local time before adding it to the Database in SQL Server.

We are migrating SQL Server system into Oracle implementation.
The application design date type:
SQL Server is achieved with DATETIME datatype EMPLOYEE(EMPLOYEE_HIRED DATETIME). Some of the columns contains time component as well till seconds.
Oracle is achieved with DATE datatype EMPLOYEE(EMPLOYEE_HIRED DATE). As we know, oracle date can hold time component as well
While migrating data from SQL Server to Oracle using SSIS, The system is defaulting it to TIMESTAMP datatype of oracle. Can this be defaulted to DATE?
There are around 1000+ such columns.
Do we need to address them manually through data conversion tool box? Can this be automated?
I Used SELECT TO_CHAR(sysDate,'dy') FROM DUAL In oracle and I want to get the same output in SQL Server. I tried several ways and I want to know the date style value for this format.
CONVERT(VARCHAR(max),'2017-03-06T00:00:00.000',<DateStyle>)
Isn't there a way to configure Sql Server Management Studio to, in query results, display the value of a DateTimeOffset column in the client's local timezone, instead of UTC?
Example: I'm in timezone +02:00. A value is stored as 2016-07-27 22:00:00.0000000 +00:00. Currently, this value is displayed as such in query results. I want it to be displayed (formatted) as 2016-07-28 00:00:00.0000000 +02:00 when executing this query on SSMS on my machine.
Currently I'm manually using something like SWITCHOFFSET(CONVERT(datetimeoffset, <DateColumn>), DATENAME(TzOffset, SYSDATETIMEOFFSET())) which is obviously very cumbersome.
If I'm not mistaken, in Oracle the NLS parameters on session level could be used for this. Is there something similar in Sql Server?
Neither SQL Server nor SSMS have any ability to work with the concept of a "session time zone" (like Oracle, MySql, etc. do).
Also, it wouldn't make sense to automatically convert the offset anyway, as the offset is actually part of the stored datetimeoffset value.
If you're using SQL Server 2016, or Azure SQL Database, you can use the new AT TIME ZONE statement, as in:
SELECT yourdto AT TIME ZONE #thetimezoneid
Otherwise, consider using my SQL Server Time Zone Support project.
Neither of which can give you the system's time zone ID. You must know which time zone you want to work with.
We have just put an application into production which is hosted on AWS using their SQL Server RDS.
We have discovered that the database is set to UTC time, where our local development database isn't.
For example. I'm trying to insert a date of 2016-06-27 08:00. This works fine on our local server, but on AWS, the date is set to 2016-06-26 22:00
I'm trying to replicate the problem on our local server, and I changed the server's timezone to UTC, but the date gets inserted as 2016-06-27 08:00, but I should now expect it to be inserted as 2016-06-26 22:00.
Is there some SQL Server setting I need to change to have a date automatically converted to insert UTC?
The Sql Server DateTime datatype doesn't know anything about timezone. The time inserted is determined by the application posting the time. So this issue is going to be in your application, not in the database.
My recommendation would be to either:
Store all DateTime's as UTC converting them in the application before saving
Use the DateTimeOffset type which stores the timezone information as well as the time
I already asked a similar question but I didn't get the answer I want. (It's my mistake!)
I have a website with a SQLServer 2008R2 database located in one country (US for example).
Many clients from different countries access to this website. All datetime datatypes are datetimeoffset. The datetime are saved using sql server datetime in US.
What should I do to convert the dates according to the client datetime zone and do I need to save the time zone different in a table to be able to convert the datetime from the database to the client?
I would store the data as UTC (and in fact I mandate that our servers are all set to UTC time with no DST adjustments - not only does this prevent gaps and overlaps twice a year, but it also makes job scheduling etc. much more predictable and reliable).
You can easily convert UTC data to any other time zone. You can use a calendar table to get the offset correctly and to account for things like DST.

Important: DATETIMEOFFSET is not DST-aware!
