Hypothetically, you could travel into the future at a faster rate than sixty seconds per minute if you move at relativistic speeds, although it's a one-way trip, via time dilation, according to Einstein's general and special relativity.
Time travel via traversable wormholes is also theoretically possible, but (a) we have yet to confirm that those exist, (b) they would be damn near impossible to construct or to find if they did exist, and (c) A full understanding of traveling through time via wormholes would have to include quantum effects. For each paper I've read, each time such a hypothetical system was modeled with an approximation of quantum effects (in addition to the relativistic character of the wormholes), the conclusions in regards to wormholes’ ability to allow objects to travel through time were inconclusive. We definitely need more information and a better theoretical understanding of the underlying physics, particularly on the quantum level.
There are also several models which allow doe backwards time travel; obviously all of Newton's equations are time-reversible, since replacing t with -t in each function dependent on time describes a physically possible process, only in reverse. If you can drop an egg and let it shatter, it's possible for the reverse to happen. However, Humpty-Dumpty doesn't put himself back together again because of entropy; the arrow of time, prodded by statistical necessity, prods things forward because it's vanishingly unlikely to go backwards. Kurt Godel also discovered a solution to Einstein's relativity equations which allowed for backwards time travel, although it does not seem that his model correlates very well with the universe we find ourselves in.
