 *   The utime() system call changes the access and modification times of

 *   are set to the current time.
 *
 * Input Parameters:
 *   path  - Specifies the file to be modified
 *   times - Specifies the time value to set
 *
 * Returned Value:
 *   Upon successful completion, 0 shall be returned. Otherwise, -1 shall

 *   times shall not be affected.
