As described in the previous lesson, sloppy quorum means multiple conflicting values against the same key can exist in the system and must be resolved somehow. Let's understand how this can happen.

What is clock skew?

On a single machine, all we need to know about is the absolute or wall clock time: suppose we perform a write to key k with timestamp t1 and then perform another write to k with timestamp t2. Since `t2 > t1
