This is probably not the answer you were expecting but ...

Yes! Both people and objects travel in time. If you think about it, you are doing it right now.

But to answer your intended question the answer is still yes. Einstein produced a theory that the faster you travelled the more compressed time became and therefore the slower time would become on your time travelling ship in comparison to the planet you left. It's called the theory of ordinary relativity.

This isn't a theory anymore. Satellites in space used for SATNAV have a built in time corrections to negate the effects of time dilation as proposed by Einstein. The time corrections are in the order of millionths of a second but without these corrections the SATNAV system would be grossly inaccurate. Furthermore humans who have travelled at high speed in space and the upper atmosphere suffer this loss of time too. They are a microscopic amount younger than they ought to me had they stayed on earth.

This is achieved at speeds that are only a few tens of thousands of miles per hour. If we could go faster toward the speed of light Einstein predicted that the effect would become exponentially exaggerated. Unfortunately he also predicts that the amount of energy required to approach the speed of light would become exponential too. So it's unlikely that we will achieve this anytime soon but the possibility to manipulate time is real.
