I don't think so <g>. If that were so, why was Hermione so seriously 
warned against changing time? My understanding of JKR's form of TT 
is that it *is* possible to change time. That is, it was entirely 
possible for future!Harry to enter Hagrid's hut while the past!Harry 
(and Hermione and Ron) was there. If he had done that, he would have 
changed the future (i.e., the present from which he came). 
However, because they were aware of this possibility, and tried hard 
not to change the course of events, they returned to an unchanged 
future/present. 
To give a grim example of returning to a changed future/present: 
Let's say that Harry had entered the hut, and that the trio were so 
shocked by seeing a second Harry, they ran screaming to tell DD. DD 
in his turn thinks that there is some black magic involved and tries 
to perform some complex and dangerous spell that results in his own 
death. So, when future!Harry and Hermione return to the sick room, 
Ron isn't there (never having been hurt) and they see Poppy weeping 
over DD's dead body. 
*Of course*, this is as full of paradox - if future!Harry bursts 
into the hut and past!Harry encounters him, how come he doesn't have 
the memory of that? But then, TT *is* paradoxical - there is no way 
(other than the splitting time lines theory) to make it entirely 
logical.
