One way to synchronize a system of identical (and well-running) clocks is to use one master clock to set the other clocks, and then move the clocks to their various locations. What is a potential problem with this approach that was mentioned in the lecture?

Consider two identical light clocks, designed as explained in lecture. Bob has one, and Alice takes the other on her spaceship and flies by Bob at speed V. Bob observes Alice’s clock. What is the relationship between a certain amount of elapsed time on Bob’s clock and the corresponding elapsed time on Alice’s clock, as observed by Bob (where γ represents the Lorentz factor)?
