Something I’d learned from my father

My dad was a navigator during World War II. He knew a lot about celestial navigation, time zones and the International Dateline.
I once asked him if one traveled fast enough and could cross the International Dateline backwards – repeatedly – would they have to subtract a day each time . . .
And as a result, would one end up traveling back in time?
He said,
Yes.
