One common question that often arises when working with SQL Server is how to retrieve the current time zone. In this article, we will explore the various ways to obtain the current time zone in SQL Server.
Before we dive into the details, let’s answer a simple question: How many different time zone labels does SQL Server 2019 support? The answer to this question will be revealed as we explore the different methods to retrieve the current time zone.
Method 1: CURRENT_TIMEZONE()
The first method involves using the CURRENT_TIMEZONE() function. This function returns the current time zone offset as a time zone offset string. For example:
SELECT CURRENT_TIMEZONE();
This query will return the current time zone offset in the format ‘+hh:mm’.
Method 2: SYSDATETIMEOFFSET()
The second method makes use of the SYSDATETIMEOFFSET() function. This function returns the current system date and time, including the time zone offset. For example:
SELECT SYSDATETIMEOFFSET();
This query will return the current system date and time along with the time zone offset.
Method 3: sys.time_zone_info
The third method involves querying the sys.time_zone_info system view. This view contains information about the time zones supported by SQL Server. For example:
SELECT *
FROM sys.time_zone_info;
This query will return a list of all the time zones supported by SQL Server, along with their respective offsets and labels.
By using these methods, you can easily retrieve the current time zone in SQL Server and gain a better understanding of the time zones supported by the system.
