In addition to stretching your relative time to incredible lengths by mounting a high-velocity rocket, you can also slow down time by being near a Big Beautiful Gravity Well. Any heavyweight plump mass causes a warp in space-time in which time slows down. Spending some quality time with one of these well-cushioned beauties would cause time to move slower (by about 30 percent on your typical Big Beautiful Neutron Star), although you'd think that time was still just flying by. After returning to space from your rendezvous of about seven years, you'd find that ten years would have passed on Earth.
