One approach:


f[x_, y_, t_] = Sqrt[x^2 + y^2 + t^2]*Exp[I*t];


Module[{func,
  xmin = -1, ymin = -1, tmin = -1,
  xmax = 1, ymax = 1, tmax = 1,
  xstep = .1, ystep = .1, tstep = .1},
 Graphics3D[
  Flatten[
   Table[
    {Hue[Arg[func = f[x, y, t]]],
     Opacity[1 - Abs[func]],
     EdgeForm[],
     Cuboid[{x, y, t},
      {x + xstep, y + ystep, t + tstep}]},
    {x, xmin, xmax - xstep, xstep},
    {y, ymin, ymax - ystep, ystep},
    {t, tmin, tmax - tstep, tstep}]],
  Axes -> True,
  AxesLabel -> (Style[#, 18] & /@
     {"x", "y", "t"})]]
