The question I've always had about Planck time is about the "clock". If you and I observe something move and we were able to do so at Planck resolution, would our ticks be synchronized?

Can you phrase that question in a way that takes relativity into account? In particular, what do you mean by ticks being synchronized between two observers, when there's no such thing as objective simultaneity?

Two observers in the same inertial frame can share a clock, can't they?

I believe so. I had assumed you were referring to the general case, sorry about the misunderstanding.
