==Abstract==

In this paper we examine the recently introduced Dvali-Gabadadze-Porrati (DGP) gravity model. We use a space-time metric in which the local gravitation source dominates the metric over the contributions from the cosmological flow. Anticipating ideal possible solar system effects, we derive expressions for the signal time delays in the vicinity of the Sun, and for various ranges of the angle ''theta'' of the signal approach.  The time contribution due to DGP correction to the metric is found to be proportional to ''b<sup>3/2</sup>/c<sup>2</sup>r<sub>0</sub>''. For ''r<sub>0</sub>'' equal to 5 Mpc and ''theta'' in the range [-''Pi/3'', ''Pi/3''], ''delta t'' is equal to 0.0001233 ps.  This delay is extremely small to be measured by today's technology, but it could be probably measurable by future experiments.
