SYNOPSIS
       #include <sys/time.h>

       int utimes(const char *path, const struct timeval times[2]);


DESCRIPTION
       The  utimes()  function  shall set the access and modification times of
       the file pointed to by the path argument to  the  value  of  the  times
       argument.  The utimes() function allows time specifications accurate to
       the microsecond.

       For utimes(), the times argument is an array of timeval structures. The
       first array member represents the date and time of last access, and the
       second member represents the date and time of  last  modification.  The
       times in the timeval structure are measured in seconds and microseconds
       since the Epoch, although rounding toward the nearest second may occur.

       If the times argument is a null pointer, the  access  and  modification
       times of the file shall be set to the current time.  The effective user
       ID of the process shall match the owner  of  the  file,  or  has  write
       access  to  the file or appropriate privileges to use this call in this
       manner. Upon completion, utimes() shall mark the time of the last  file
       status change, st_ctime, for update.

RETURN VALUE
       Upon successful completion, 0 shall be returned. Otherwise, -1 shall be
       returned and errno shall be set to indicate the  error,  and  the  file
       times shall not be affected.

ERRORS
       The utimes() function shall fail if:

       EACCES Search  permission  is denied by a component of the path prefix;
              or the times argument is a null pointer and the  effective  user
              ID of the process does not match the owner of the file and write
              access is denied.

       ELOOP  A loop exists in symbolic links encountered during resolution of
              the path argument.

       ENAMETOOLONG
              The length of the path argument exceeds {PATH_MAX} or a pathname
              component is longer than {NAME_MAX}.

       ENOENT A component of path does not name an existing file or path is an
              empty string.

       ENOTDIR
              A component of the path prefix is not a directory.

       EPERM  The  times  argument  is  not  a  null  pointer  and the calling
              process' effective user ID has write access to the file but does
              Pathname  resolution of a symbolic link produced an intermediate
              result whose length exceeds {PATH_MAX}.

       None.

APPLICATION USAGE
       For applications portability, the utime() function should  be  used  to
       set file access and modification times instead of utimes().

RATIONALE
       None.

FUTURE DIRECTIONS
       This function may be withdrawn in a future version.
