insist on you/your being on time

[Marika33]

Are all of these correct or some of them unnatural? If all are correct, do they mean the same thing?

1. I insist on you being on time.
2. I insist on your being on time.
3. I insist (that) you be on time.

The third one is okay only with "that".

They all mean the same thing.

 

[probus]

With respect, I disagree @Tarheel. Number 3 sounds fine to me without "that". But I do agree all three have the same meaning.

The second sentence is more formal.
