An extension of the usual $ωt$-scaling is proposed. Simulational data from the three-dimensional Ising spin glass agree with this new scaling form and moreover reproduce well the scaling functions explicitly calculated for systems satisfying local scale-invariance. There is also a qualitative agreement with existing experimental data.19 pages, 2 figures, to appear in special issue of J. Phys. Cond.
