Does the age of the universe (13.7 billion years) account of the time dilation factor caused by velocity of the earth through space relative to a object with zero velocity?

As an object gets closer to the speed of light, there is a time dilation factor, and Earth is usually used as zero. however the earth is moving within space, so does the age of the universe (13.7 billion years) include our time dilation factor? if not,what is the age of the universe for a object with zero velocity?

There is a reference frame in which the cosmic microwave background is most isotropic, that Earth is moving about 600 km/s relative to. There are no special physics in this frame, it is not preferred, but in it the universe is oldest and that frame is what that measurement corresponds to. However, the difference between that frame and the Earth's frame, in terms of relativistic effects, is smaller than the uncertainty on the measurement.
