The l_fp timestamps must be unsigned since they are just counting seconds from the beginning of the epoch. That means that there's an assumption somewhere in NTP that differences between those timestamps, which are necessarily signed unless you want to carry the direction of the difference as a separate datum, are limited to less or equal than half the range of that type. If you compute that difference in modulo arithmetic, then timestamp differences between two adjacent epochs are still valid as long as the true time difference is less than half an epoch. In other words, you don't have to explicitly check for the epoch of either timestamp if you assume that these are less than 68 years apart.
