Run command at specific time

[clubby789]

I was wondering what the best way would be to run a command at a specific time. I was considering having an infinite loop that checks constantly but this doesn't seem like a good idea.

You can (it isn't a full list)
timer.Create
Loop of timer.Simple
Hooks with os.time cooldowns

I want to run an action once per day just after 8:30 PM; would this work?
local function checkTime()
    if (os.date("%H") = "20") and tonumber(os.date("%M")) >= 30 and tonumber(os.date("%M")) <= 35 then
        -- Perform action
        timer.Stop("830Timer")
        timer.Create("RestartTimer", 1000, 1, function() timer.Start("830Timer") end)
end

hook.Add( "Initialize", "Start Timer", function() timer.Create( "830Timer", 60, 0, checkTime ) end)

As an option
You can get distance between os.time and next 8:30 and set first timer.
