Is it possible to say "Do you know when he is back(or when he comes back)? instead of the following?
My grammar book says that future tense can't be replaced by present tense in noun clauses.
gz13)Do you know when he will be back?
You mean these two are fine when referring to the future?
1. Do you know when he is back?
2. Do you know when he comes back?
