 * Name: futimens
 *
 * Description:
 *   futimens() update the timestamps of a file with nanosecond precision.
 *   This contrasts with the historical utime(2) and utimes(2), which permit
 *   only second and microsecond precision, respectively, when setting file
 *   timestamps.
 *
 * Input Parameters:
 *   fd  - Specifies the fd to be modified
 *   times - Specifies the time value to set
 *
 * Returned Value:
 *   On success, futimens() return 0.
 *   On error, -1 is returned and errno is set to indicate the error.
