3 clocks thought experiment - Absolute vs. relative aspects?

[QUOTE="PeterDonis, post: 6899827, member: 197831"] It doesn't. The observed object does not feel any change at all in its aging or experience of time. You, right now, are moving at more than 99% of the speed of light relative to cosmic ray particles coming in to Earth from outer space. Do you feel any change in your aging or experience of time? Time dilation is something the [I]observer[/I] calculates (note that I did [I]not[/I] say "sees", because what the observer actually [I]sees[/I], in the light signals coming to him from the observed object, is described by the relativistic Doppler shift formula, not the time dilation formula). The observed object doesn't even "know" that it's being observed. [/QUOTE]
