"CoolDownCount"

[Zonx]

In EQ2 terms, this would be a "Recast Timer" and would require SOE to add Dynamic Data objects to the XML that don't already exist. The nearest thing to it are the "Duration Timers" recently added to the Maintained window.

It might be possible to enable a mouseover effect that displays the refresh progress as a percentage, but that wouldn't give you an actual time value, and it wouldn't update until you moused over the icon.
