Re: boot time

[Peter Canning <canning@vitria.com>]

Has anyone else noticed that the 991021 version of pmacpow doesn't seem
to work when specifying an absolute time?

The usage message says:

pmacpow [-u] [-w|e|q] [-d DAY] HH:MM
pmacpow +value[mhd]
        u: RTC is in universal time
        w: only on weekdays
        e: only on weekends
        q: quiet mode
        d: specify day of week (0..6); 0 represents Sunday
        value: time in sec or min or hour or day ahead of current time

However, when I type:
    pmacpow 06:20
it prints:
    will be up again Sat May 11 22:04:05 2002
which appears to be 6 seconds in the future.

Examining the program in the debugger leads me to believe that the logic
in lines 236-257

    236         tmp = strsep(&timestr, ":");
    237         if (tmp && (strlen(tmp) != strlen(argv[optind]))) {
    238                 if (!tmp || !timestr)
    239                         usage();
    240                 hour = atoi(tmp);
    241                 min = atoi(timestr);
    242                 sec = 0;
    243         } else {
    244                 timestr = argv[optind];
    245                 sec = strtol(timestr, &tmp, 10);
    246                 if (tmp) {
    247                         switch (tolower(tmp[0])) {
    248                         case 'd': 
    249                                 sec *= 24;
    250                         case 'h': 
    251                                 sec *= 60;
    252                         case 'm': 
    253                                 sec *= 60;
    254                                 break;
    255                         }
    256                 }
    257         }



doesn't work as intended because strsep modifies both timestr and the
string.  The program doesn't enter the first branch of the if statement
when it should.

The earlier 991019 version works fine, but doesn't support the +value
style of usage.
