Re: [MacPerl] MacPerl & timelocal....

Too much going on today... let's try this again.

}Doesn't look like it.  In fact, it looks like your Sun is wrong.

}
}All 1 bits?

On the Mac (I thought it was your Sun giving this) this is almost certainly
a symptom of a bug in Perl 5.002.  There are comparisons in timelocal.pl
that have to be made floating point in order to get them to evaluate
properly.  I have a fixed timelocal.pl (which is what I used below since I
have it installed in my MacPerl lib folder) at
<ftp://mors.gsfc.nasa.gov/pub/MacPerl/Scripts/Fixed_Library_Routines/>.
What you should really do, though, is instead of using the ancient
timelocal.pl use Time::Local, which Matthias has already fixed.

}} @timearray = localtime(time);
}} ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = @timearray;
}} printf ("raw local time is %02d/%02d/%04d %02d:%02d:%02d %d %d %d\n",
}}          $mon+1,$mday,1900+$year,$hour,$min,$sec,$wday,$yday,$isdst);
}} $ltime = &timelocal(@timearray);
}} printf ("timelocal = %8x\n",$ltime);
}
}Here's what I get under MacPerl:
}
}raw local time is 03/07/1997 17:05:18 5 65 0
}timelocal = af45a6ee
}
}and on my Sun (Perl 5.003, SunOS 4.1.4)
}
}raw local time is 03/07/1997 17:07:46 5 65 0
}timelocal = 332091b2
}
}I haven't checked to see whether the hex is right, but it should be on both.
}
}I don't know exactly what you're expecting.  Looks to me like Perl on your
}Sun may be messed up; notice the message about printf.  You do realize that

And I missed the fact that you were using -w, hence the message about
printf.  It's been one of those days.

}the Unix and Mac zeroes of time are different, so the last hex numbers will
}differ substantially?
