Where can I find a white noise machine with time projection?

I used to have a sound machine with a light on it and several sound options including thunder&rain, white noise, waterfall, and others. I enjoy all the sounds, but my favorite was always plain, white noise. So I've been looking for a sound machine that has the time projection and alarm, but I cannot find one with white noise as an option. Is it maybe just a given, so they dont list it? I really need to find one. Help, please!
