Time (logical clocks) should not be allowed to st in addition to still or jump Let’s be more careful ( in addition to ambitious): Logical clocks should always move as long as ward Sometimes faster, sometimes slower is OK. But there should be a minimum in addition to a maximum speed.As close to correct time as possible!Time Must Behave!Local Skew Tree-based Algorithms Neighborhood Algorithms e.g. FTSP e.g. GTSPBad local skewSynchronization Algorithms: An Example (“Amax”)Question: How to update the logical clock based on the messages from the neighbors Idea: Minimizing the skew to the fastest neighbor
