Twitter’s future privacy plans include the ability to hide tweets from users after a set amount of time.

The way it will work is actually quite simple; rather than have everyone see your entire timeline, you will be able to set it in such a way that users will stop seeing tweets that are older than 30, 60 or 90 days, or an year, if you like, according to Bloomberg.
