Syntax

TODATETIMEOFFSET ( datetime_expression , timezoneoffset_expression )

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.
