TODATETIMEOFFSET ( expression , time_zone )

Arguments

• expression
  Is an expression that resolves to a datetime2 value.

  [!UWAGA]

  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.

  [!UWAGA]

  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.

DECLARE @todaysDateTime datetime2;
SET @todaysDateTime = GETDATE();

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

B. Changing the time zone offset in minutes
