This is a very Simple Timed Bans snippet. If you want to ban someone from a channel for a certain time limit, right click their nickname and Select 'Timed KickBans'. Next, you click on the time limit that you want the person to be banned for. Next, you will be prompted to enter a reason for kicking them. After you've kick-banned the person out of the channel, the timer will start. At the appropriate time, you will automatically unban the person you banned.
