Change x-axis units in table plot

Hi all,

I have a 3d model of diffusion from a source and am calculating surface integrals of flux over particular features in my geometry. This outputs a table of total flux vs. time point which can then be plotted in a 1d plot group table plot. However, the default output of this is with respect to seconds as used in the time dependent solver and I cannot figure out any way to change the x-axis units to something else for display. When my changes of interest occur on the order of many hours, it is inconvenient to look at things in seconds. Thanks!
