Arguments:

• slot - An action bar slot (number, actionID)

Returns:

• start - The value of GetTime() at the moment the cooldown began, or 0 if the action is ready (number)
  
• duration - The length of the cooldown, or 0 if the action is ready (number)
  
• enable - 1 if a Cooldown UI element should be used to display the cooldown, otherwise 0. (Does not always correlate with whether the action is ready.) (number)

Examples:

for i=1,120 do
local start,duration,enable = GetActionCooldown(i)
if start > 0 and enable == 1 then
local actiontype,id,subtype = GetActionInfo(i)
local name

if actiontype == "spell" then
name = GetSpellName(id, "spell")
elseif actiontype == "item" then
name = GetItemInfo(id)
elseif actiontype == "companion" then
name = select(2, GetCompanionInfo(subtype, id))
end

local timeLeft = math.floor((start + duration) - GetTime())
local output = string.format("Cooldown on %s %s (%s seconds left)", actiontype, name, timeLeft)
