4962 | * | |
4963 | * some nasty thing goes on if we were to do 'a - b' between two utime_t, | |
4964 | * and 'a' happens to be lower than 'b'; so we use double instead. | |
4965 | * | |
4966 | * latency is always expected to be >= 0. | |
4967 | * | |
4968 | * delta, the difference between theirs timestamp and ours, may either be | |
4969 | * lower or higher than 0; will hardly ever be 0. | |
4970 | * | |
4971 | * The absolute skew is the absolute delta minus the latency, which is | |
4972 | * taken as a whole instead of an rtt given that there is some queueing | |
4973 | * and dispatch times involved and it's hard to assess how long exactly | |
4974 | * it took for the message to travel to the other side and be handled. So | |
4975 | * we call it a bounded skew, the worst case scenario. | |
4976 | * | |
4977 | * Now, to math! | |
4978 | * | |
4979 | * Given that the latency is always positive, we can establish that the | |
4980 | * bounded skew will be: | |
4981 | * | |
4982 | * 1. positive if the absolute delta is higher than the latency and | |
4983 | * delta is positive | |
4984 | * 2. negative if the absolute delta is higher than the latency and | |
4985 | * delta is negative. | |
4986 | * 3. zero if the absolute delta is lower than the latency. | |
4987 | * | |
4988 | * On 3. we make a judgement call and treat the skew as non-existent. | |
4989 | * This is because that, if the absolute delta is lower than the | |
4990 | * latency, then the apparently existing skew is nothing more than a | |
4991 | * side-effect of the high latency at work. | |
4992 | * | |
4993 | * This may not be entirely true though, as a severely skewed clock | |
4994 | * may be masked by an even higher latency, but with high latencies | |
4995 | * we probably have worse issues to deal with than just skewed clocks. | |
