No, the phase constantly changes at the same rate as the frequency.Do the phase of wave at x=0 bears a constant value for all values of t?"

Yes, the phase at point Q is the same as the phase at point P.Let Q be another point on the same source(monocromatic) , the phase of wave from point Q at t=0, have same value as the value of phase of wave from P at t=0?"
