How is SQL Server Time Zone different from system time?
It inherits the system time from Windows, and uses that in realtime. For example, if you install SQL Server while the system is in one time zone, and you change the server to a different time zone, the next time you call GETDATE () it will reflect the new time zone. – Aaron Bertrand Jan 25 ’13 at 15:25 thank you Aaron!!!.
When to use at Time Zone hint in SQL Server?
Sometimes though, it may be necessary to query data directly and see what the local date and time is, or calculate the date and time in another region. For this use-case, we can use the AT TIME ZONE hint, which was introduced in SQL Server 2016.
How to convert date time to Time Zone?
Let us first declare a value and store a UTC time in it. Right after that we will display that with different timezone offsets. There are many different timezones available out there which this function support and you can check all of them with the help of the following command. Well, that’s it for today.
How does the at time zone function work?
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. AT TIME ZONE implementation relies on a Windows mechanism to convert datetime values across time zones.

Where do I find time zone information in SQL?
We can also use a Transact-SQL (T-SQL) query against the system view sys.time_zone_info, which uses the information from the registry hive. This is the recommended method if you do not have access to the registry hive.
