the clock on a fast spacecraft leaving earth measures proper time on earth if it was correctly synchronized to earth time before depature.

It will be slightly different due to the time dilation caused by the spacecrafts acceleration and distance from the center of gravity of the Earth.

How fast is fast? If the velocity of the spacecraft is close to that of velocity of light in vacuum, there will be time dilation effects and the clock will run slower and the error will be significant when it returns to earth.

true if the spacecraft JUST left earth. The time difference will only take place much later!

True. Regardless of the time dilation paradox, time actually progresses at the same rate on the spaceship as it does on Earth. The paradox is the mutual perception that time is slowing for the other because of, for want of a better term, lightspeed lag.

At earth in condition of rest - true.
When the speed increases, it will start losing time.
