Syntax

TODATETIMEOFFSET ( expression , time_zone )

Arguments

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.

time_zone
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 time_zone.

[!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 argument.

Examples

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 2007-08-30 15:51:34.7030000 -07:00

B. Changing the time zone offset in minutes

DECLARE @todaysDate datetime2;  
SET @todaysDate = GETDATE();  
SELECT TODATETIMEOFFSET (@todaysDate, -120);  
-- RETURNS 2007-08-30 15:52:37.8770000 -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.

DECLARE @dateTime datetimeoffset(7)= '2007-08-28 18:00:30';  
SELECT TODATETIMEOFFSET (@dateTime, '+13:00');  
-- RETURNS 2007-08-28 18:00:30.0000000 +13:00
