But then again, probably not so long.
I've always liked those science fiction stories where the earlier, slower ships get frog jumped by the technical achievements back home.
When the first sent load of colonists arrive, they find a bustling Earth built community had arrived 1,000 years before them!
The inner exoplanet, HD 260655 b, is around 1.2 times the size of Earth and twice the mass of Earth, and orbits the star every 2.8 days. The outer world, HD 260655 c, is 1.5 times the size and thrice the mass of Earth, and has a 5.7-day orbit.
Gives a whole new meaning to the concept of years: a 2.8 day year and a 5.7 day year. I assume that's in Earth days. Depending on the rate of rotation, the day there might be longer than the year!
