You are missing your ()'s. Also, it should be RETURNS for the first RETURN.
CREATE FUNCTION function_name
(
)
RETURNS DATETIME
AS
BEGIN
DECLARE @var datetime
SELECT @var=CURRENT_TIMESTAMP
RETURN @var
END
When you create a function, the return type should be declared with RETURNS, not RETURN.
Its the () you are missing after function name and also use RETURNS after function name.
