ntp/pps: use y2038 safe types in pps_event_time
The pps_event_time uses two 'timespec' structures internally, which suffer from the y2038 problem. The uses of this structure are fairly self-contained in the pps code, so this replaces them all at once. Unfortunately, this includes the sfc ethernet driver aside from the pps subsystem, so we change that one as well. Both touch the same data structure, and there probably is no good way to split the patch into smaller units. Acked-by: Richard Cochran <richardcochran@gmail.com> Acked-by: David S.
