Emne: [Getdp] Explicit time

Dear all
Is it possible to include an explicite time variable in the Euler and Newmark time schemes? The spatial variables can be included by X[], Y[], and Z[], but there does not exist a T[] or time[].
I would like to solve a harmonic damped oscillator with a damping term: -dt^2(phi) -i*g*dt(phi)-k*phi = f(t), where f(t) is the driving term and g,k are constants (or spatial operators).
