Not noticeably faster, but yes it’s possible that other planets may experience time a bit slower than us. Time slows down with lots of mass nearby (this is what causes gravity). So if another planet was orbiting near a neutron star, it’s time would go slightly slower relative to our point of view.
There is also relativity, where if the planet is moving away/towards us very fast, its time will be relatively slower. For the real mind trip, we’d also be going slower from their point of view! There will be planets out there whose time goes eg 0.000000000000001% faster than us, because they have less nearby mass.
