To be successfully sent back in time you have to overcome at least two known barriers which are yet to be proven as surmountable by any of the scientific fields. The first is the act of storing physical matter as energy for transportation over any distance, as well the complementary task of reconstituting the encoded energy back into a living physical form.

The second, if the big bang theory is to be adopted, is due to universal expansion resulting in an unrecoverable loss of entropy compounding with each passing second. Meaning unless our universe suddenly starts making GBS threads out pure unadulterated photons out of dark nothingness thereby able to keep up with its ever-expanding but cooling fatbody, having your time machine appear in a more energetic environment than in this current moment is a slight contradiction.

Sorry OP, but the sad truth is that is it simply impossible for you to rewind the hands of time in order to fulfill your incestuous desires with each one of your long-dead uncles.
