We first describe a one-parameter family of unconditionally stable third-order timeintegration schemes for the convection-diffusion equation: ut + cux = vuxx, based on the extended trapezoidal formulas of Usmani and Agarwal [1]. Interestingly, there exists a method that is .fourth order as well as u
