  The Two-time model (2T model) has six dimensions with two dimensions of time,
has a Dilaton particle that makes the symmetry breaking differently from the
Standard Model. Assuming a soft break of $SP(2,R)$ symmetry, the 2T extension
can give a suitable picture of the matter-antimatter asymmetry by the
Baryogenesis scenario. By reducing the 2T metric to the Minkowski metric (1T
metric) and using a new form of Dilaton potential, we consider the electroweak
phase transition picture in the 2T model with the Dilaton as a trigger. Our
analysis shows that Electroweak Phase Transition (EWPT) is a first-order phase
transition at the $200$ GeV scale, its strength is about $1 - 3.08$ and the
mass of Dilaton is in the interval $[345,625]$ GeV. Therefore, the 2T-model
indirectly suggests that extra-dimension can also be a source of EWPT.
