/*
 * Sample program for utime system call  - No.30
 *
 * utime, utimes - change access and/or modification times of an inode
 *
 * Synopsis
 *     #include <sys/types.h>
 *     #include <utime.h>
 *
 *     int utime(const char *filename, sturct utimbuf *buf);
 *
 *     #include <sys/time.h>
 *
 *     int utimes(char *filename, sturct timeval *tvp);
 *
 * Description
 *     utime changes the access and modification times of the
 *     inode specified by filename to the actime and modtime
 *     fields of buf respectively. If buf is NULL, then the
 *     access and modification times of the file are set to the
 *     current time. The utimbuf structure is:
 *
 *         struct utimbuf {
 *             time_t actime;  * access time *
 *             time_t modtime; * modification time *
 *         };
