You might be hard-pressed to find a reason to use this. But, if you want some game mechanic to be delayed by some specific amount of time in seconds or fractions of a second, you can do this using Events.LocalMachineAppUpdate. It's used by the tutorial system to decide when it's time to annoy you with some help...
Test code:
Output:
You can see it's firing many times each second. Obviously, that's a lot of overhead that you don't want for very long, certainly not between turns. If you had some need for this over a long time (though I can't really imagine why you would) you could remove the listener and add it back later:
The first arg (tickCount) is more useful here. It keeps counting (in 1/1000's of a second) even when the listener is disconnected. Of course, if you are timing something over hours you should just check os.clock() each turn. But this Event lets you time some graphical or sound UI in seconds or fractions of a second if you need that.
[Edit: I had previously suggested that you use Events.LocalMachineAppUpdate.RemoveAll() to shut off tutorial overhead. whoward69 points out below that setting No Advice in options does shut down these checks, so no need to worry about that.]
Test code:
Code:
local bStart = false
local tickStart = 0
local cumIncrement = 0
local function LocalMachineAppUpdateListener(tickCount, timeIncrement)
if bStart then
cumIncrement = cumIncrement + timeIncrement
print("LocalMachineAppUpdateListener: ", (tickCount - tickStart) / 1000, cumIncrement)
else
tickStart = tickCount
bStart = true
end
end
Events.LocalMachineAppUpdate.Add(LocalMachineAppUpdateListener)Output:

, are you saying we are better off disabling this event via Events.LocalMachineAppUpdate.RemoveAll()....
