5046 | * and 'a' happens to be lower than 'b'; so we use double instead. | |
5047 | * | |
5048 | * latency is always expected to be >= 0. | |
5049 | * | |
5050 | * delta, the difference between theirs timestamp and ours, may either be | |
5051 | * lower or higher than 0; will hardly ever be 0. | |
5052 | * | |
5053 | * The absolute skew is the absolute delta minus the latency, which is | |
5054 | * taken as a whole instead of an rtt given that there is some queueing | |
5055 | * and dispatch times involved and it's hard to assess how long exactly | |
5056 | * it took for the message to travel to the other side and be handled. So | |
5057 | * we call it a bounded skew, the worst case scenario. | |
5058 | * | |
5059 | * Now, to math! | |
5060 | * | |
5061 | * Given that the latency is always positive, we can establish that the | |
5062 | * bounded skew will be: | |
5063 | * | |
5064 | * 1. positive if the absolute delta is higher than the latency and | |
5065 | * delta is positive | |
5066 | * 2. negative if the absolute delta is higher than the latency and | |
5067 | * delta is negative. | |
5068 | * 3. zero if the absolute delta is lower than the latency. | |
5069 | * | |
5070 | * On 3. we make a judgement call and treat the skew as non-existent. | |
5071 | * This is because that, if the absolute delta is lower than the | |
5072 | * latency, then the apparently existing skew is nothing more than a | |
5073 | * side-effect of the high latency at work. | |
5074 | * | |
5075 | * This may not be entirely true though, as a severely skewed clock | |
5076 | * may be masked by an even higher latency, but with high latencies | |
5077 | * we probably have worse issues to deal with than just skewed clocks. | |
