In fact, that is time travel. In the same way that you travel into the future every day, since what was the present when you woke up in the morning is now the past. In this restricted sense, yes, time travel is possible and proven.
But when people refer to time travel, they generally mean arbitrary travel to nonsequential points in time. Going from 22:00 today to 17:00 yesterday to 10:00 today.
The difference here is between floating down a river with a strong current and being able to slow down or speed up your progress a bit (the restricted sense of "time travel" that you mentioned), and taking a ship out onto the ocean and going where you want (the more typical use of the term "time travel").
