# Expiration Examples
* Below in this LUA example we will count the number of times a player has talked to an NPC, first by checking if we've got a bucket set at all, if not we will set an expiration time on it using unix time. Each time we call set_data, it will not over-ride the original expiration time unless we pass a new time parameter
```lua
function event_say(e)
if (e.message:findi("hail")) then
-- Set unique key for the bucket
local key = e.other:GetCleanName() .. "_times_talked";
-- If the bucket is empty, we need to set it
-- The first time we will set an expiration on this, current time plus one day (86400 seconds)
if (eq.get_data(key) == "") then
eq.set_data(key, '1', os.time(os.date("!*t")) + 86400);
end
local times_talked = tonumber(eq.get_data(key));
e.self:Say("You know... You've talked to me " .. times_talked .. " time(s) today, get a life will ya!");
-- Increment times talked
eq.set_data(key, tostring(times_talked + 1));
end
end
```
