POSIX now says: "Since the utimbuf structure only contains time_t variables and is not accurate to fractions of a second, applications should use the utimensat() function instead of the obsolescent utime() function."
Suggested resolution: Rewrite the last_write_time setter description to utilize utimensat() or similar.
