Server Nitro Boosting Run Out Clock

Ok, so I want to boost a server that has 3 boosts so far. I know we wont get to 15 boosts so i dont want to boost it now for no benefit of the server. So I want a clock that will say when the users that have boosted the server boosts will run out. So that if it drops down to 1 I can boost it. But i dont want to have to check every day to see if it has expired yet. Another solution to this is to give a notification of some sort when boosts have expired. Thanks for reading this, Ice Wolfy
