Doctor Bashir, I Presume? - S5-E16
Factual error: When Captain Sisko introduced the head of JAG to Bashir's parents, he pronounced "Rear Admiral Bennett" but Bennett was wearing the rank of Admiral (2 X 4 pips enclosed) instead of Rear Admiral (2 X 2 pips enclosed).
Chosen answer: No. He's given his name, that's all. Nothing there that might lead to a paradox. If he's gone into detail about his time travelling, that might cause an issue or two, but simply stating his name does nothing.
