Sure. But say you started by synchronising the time with that on the
right-hand platform clock. Bringing it to the left platform tells you
nothing in particular (you can explore the maths a bit - but don't
forget to consider how clocks on the two platforms were initially
synchronised, and how the motion through the ether affected this!). You
have to bring it back to the right platform to compare it in a simple
way, and then it has moved faster through the ether than the platform
clocks, and will be found to have slowed down overall.
