       The utime() function only allows setting file timestamps to the nearest second.  Applications should  use
       the utimensat() function instead. See <sys/stat.h>.

       The <utime.h> header shall declare the utimbuf structure, which shall include the following members:

           time_t    actime    Access time.
           time_t    modtime   Modification time.

       The times shall be measured in seconds since the Epoch.

       The <utime.h> header shall define the time_t type as described in <sys/types.h>.

       The  following  shall  be declared as a function and may also be defined as a macro. A function prototype
       shall be provided.

           int utime(const char *, const struct utimbuf *);

       Thefollowingsectionsareinformative.

       The <utime.h> header may be removed in a future version.
