main(argc,argv)
char **argv;
{
        long start, now;
        char buff[100];
        struct tm *tm;
        start=atoi(argv[1]);
        for(now=start; now < (start + 18 * 600); now+=600) {
                tm=localtime(&now);
                strftime(buff,100, "%A  %b %e, %Y  %H:%M %Z", tm);
                printf(" %13d   =  %s \n", now, buff);
        }
