Edit: I threw something into the wiki.

-- run for 5 seconds
local withinInterval = true
zo_callLater(function() withinInterval = false end, 5000) 
 
while withinInterval do
    -- something
end

Or, more asynchronous - this should call the function around 10 times

-- run for 5 seconds
local withinInterval = true
zo_callLater(function() withinInterval = false end, 5400) 
 
local function callWithinInterval()
    if not withinInterval then return end
    -- do something
    return zo_callLater(callWithinInterval, 500)
end
-- now call it
callWithinInterval()
