Variant of utime(2) with struct timespec (with ns precision) instead of time_t values; also allows for tv_nsec members the values UTIME_NOW (force update to current time) or UTIME_OMIT (allow to set either atim or mtim independently.) Provides a superset of utimes(2), futimes(2), lutimes(2), and futimens(2). Provides the same subset of utimensat(2) as does NetBSD 6. Also import utimens() and lutimeNS() from NetBSD-current.
