I dont think this is entirely accurate; if you travel close to the 
speed of light your time reference is different so that what to you 
is one hour (for example) will be several hours to someone else who 
is standing still.  Therefore, the person standing still will age 
much faster than you.  In other words, if you are traveling close to 
the speed of light you will age very slowly as compared to a person 
who is not moving, therefore you will live much longer and be able to 
experience more of the future than the person who will have a shorter 
life span.  This is not really the same as traveling into the future, 
but perhaps in some metaphysical sense it is the same thing.  And, as 
Steve says, there is no way to return to the present; as far as 
contemporary physics knows, time travels in only one direction.
