Is "Time Travel" to the future currently possible?

I was wondering if there is a realistic way that one can "travel" to the future, using today's technology.

An individual is put under cryogenic freezing and then put into an artificially induced coma. His body and mind remain preserved for over 100 years, after which time he is taken out of cryogen and is awoken. Is this scenario unrealistic with current technology? What are the limitations of this?

Another scenario I thought of is where an individual travels in space on a spaceship. After traveling for say, 3 years, he returns to earth and 100 years have passed on earth. Thereby he "traveled into the future".

Are either of the scenarios realistically plausible with our current technology or in the very near future (next 10 years)?

Also, If anyone comes up with any other "realistic" scenarios for "time travel" I would love to hear them. These are just two I thought of.
