Yes. All you have to do is crawl into a well and turn a giant wheel. Just don't knock it off it's axis. People might die as the time shifts become randomized and harder to control. Make sure you have a constant ready just in case!
And when you think about it, IF it were possible, it would be pretty useless, as your could only go FORWARD in time, but not backward. You could travel into next Saturday to get the Lottery Numbers -- but you would have no way to send them back to yourself today. if you went far enough into the future, you would reach a point where the people are so much smarter than you that you would be no more than a museum exhibit, and that is not a good way to live. or you might even go so far into the future that all humans have died -- and you would bb completely alone.
This is because TIME only goes in ONE direction -- forward. ANY kind for travel requires that "where you were" still exists when you return. So, you drive 100 miles north, then turn 180 degrees, and drive 100 miles south. you are right back where you were -- no problem, just a couple of hours older.
But with TIME, the "when you were" no longer exits. as soon as that "instant in time" is complete, it ceases to exist, and you cannot return to it. Yes you DO have only once chance to make a first impression, time CAN be wasted, and there is no time like the present time.
time travel is almost certainly impossible, but even the slightest possibility of forward time travel is useless.
Small Time travel, as if in small time durations, has been tried many times in a lab, sometimes working and sometimes not, but if we want to try out time travel on humans, we need to be very fast and get very close into Light Speed (About 300Million Meters p/sec) or get close to a powerful gravitational pole for example a black hole.
Time travel trough Worm Holes is probably true and if it is, it will throw us backwards in time.
Time dilation happens when someone's running at the speed of light when the other is attached to the runner and doesn't move. The runner will pass throw Time Dilation, causing him to somewhat time travel and It'll be younger than the person that stands when he'll come back and stop.
Because of that, time travel is possible in principle but if these theories is true, we are far from doing them.
Time dilation, due to massive gravity, excessive speed, or both will stretch rest time t into T > t. And anyone who's time line is t will find himself into the future by T - t when he returns to relative time t. [See source.]
There are all sorts of reason travel into the past is impossible. Here are but three.
Paradox. Nature and physics don't like paradoxes. If you were to travel into the past and kill your grandfather before your dad was conceived, then why are you still here?
2nd Law of Therm (entropy). Our universe is a net positive entropy closed system. To travel into the past, we would have to return it (the whole thing) back to a lower entropy state. Can't be done. We can't put Humpty Dumpty back together again.
Positive feedback [This is attributed to S. Hawking]. Like the screeching on an amplifier when a live mike gets too close to it, a loop into the then and there, from the here and now, and back again would set up a positive feedback of ambient radiant energy that would immediately overwhelm that loop and destroy it and whatever it contains.
When we talk on this topic, we most tacitly assume that whatever change I may witness using any kind of contrivance that will affect me alone and never my surroundings-neighbours-friends. So selfish a desire most hiddenly nourished!!
It is also of interest to travel back in time. But, by any means if the arrow of time say for me alone can be reversed, then how do I feel the change? Surely expecting to observe a rewinding video .
It can't happen. Because, it will violate the 'causality principle' , the principle of attainment of 'minimum PE' by any system, perpitual energy can be harnessed by cooling a cold body to the coldest with its surroundings. And it will convert the Universe in a more organized state i.e. lowering the ENTROPY from todays disorganized state. The examples of violations of the basic tenets of physical science can overflow out of this page. And other viewers can add more to it.
The most fundamental question is " Can there be any mechanism built out of our science and technology anyday that just aim to make the science ROOTLESS by cutting its basic principles?"
It can be possible.. But the machines we need to create for it are out of human ability... Well scientists say that it is possible by 3 methods... First enlarge a worm hole and travel through it.. But worm holes are infinitely small holes present everywhere.. Its barely hard to find them and and if in future if we become able to enlarge it then it is not sure that in which time period we will move... second by traveling at very high speed comparable to speed of light.. it will slow down time and we will move into future, past traveling is not possible by it... 3rd is making revolution of a super massive black hole which is said to be present on centre of our milkyway galaxy... massive object like this slow downs time... well now you know the techniques.. Tell me when time machine is ready.. :D :D

ACTUALLY -- no.

Maybe in the future.

Yes and no.
Yes into the future; no into the past.
