Transact-SQL Syntax Conventions

Syntax

TODATETIMEOFFSET ( datetime_expression , timezoneoffset_expression )  

[!INCLUDEsql-server-tsql-previous-offline-documentation]

Arguments

datetime_expression
Is an expression that resolves to a datetime2 value.

Note

The expression cannot be of type text, ntext, or image because these types cannot be implicitly converted to varchar or nvarchar.

timezoneoffset_expression
Is an expression that represents the time zone offset in minutes (if an integer), for example -120, or hours and minutes (if a string), for example '+13:00'. The range is +14 to -14 (in hours). The expression is interpreted in local time for the specified timezoneoffset_expression.

Note

If expression is a character string, it must be in the format {+|-}TZH:THM.

Return Type

datetimeoffset. The fractional precision is the same as the datetime_expression argument.

Examples

A. Changing the time zone offset of the current date and time

The following example changes the zone offset of the current date and time to time zone -07:00.

DECLARE @todaysDateTime DATETIME2;  
SET @todaysDateTime = GETDATE();  
SELECT TODATETIMEOFFSET (@todaysDateTime, '-07:00');  
-- RETURNS 2019-04-22 16:23:51.7666667 -07:00  

B. Changing the time zone offset in minutes

The following example changes the current time zone to -120 minutes.

SELECT TODATETIMEOFFSET(SYSDATETIME(), -120)
-- RETURNS: 2019-04-22 11:39:21.6986813 -02:00  

C. Adding a 13-hour time zone offset

The following example adds a 13-hour time zone offset to a date and time.

SELECT TODATETIMEOFFSET(SYSDATETIME(), '+13:00')
-- RETURNS: 2019-04-22 11:39:29.0339301 +13:00
