We adapt a calculation due to Massacand and Schmid to the coordinate independent definition of time and vacuum given by Capri and Roy in order to compute the trace anomaly for a massless scalar field in a curved spacetime in 1+1 dimensions. The computation which requires only a simple regulator and normal ordering yields the well-known result $\frac{R}{24\pi}$ in a straightforward manner., Comment: RevTeX, 13 pages, some typos corrected and an appendix added, this is the version to appear in Class. and Quantum Gavity
