The interfaces based on 'struct timespec' and 'unsigned long' seconds are no longer recommended for new code, and we are trying to migrate to ktime_t based interfaces and other y2038-safe variants. This moves all the legacy interfaces from linux/timekeeping.h into a new timekeeping32.h to better document this.
