CGI script choking on localtime function call

[nysus]

I'm stumped. I've got a script with the following three lines in it:

my $yesterday = time();
$yesterday = $yesterday - 86400;
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime($
+yesterday);

It returns a 500 Internal Server Error. I have no way of checking the error logs on this particular site and the server apparently does not have CGI::Carp installed (and I'd like to avoid installing it manually). I'm using a site on godaddy's server, Perl version 5.6. If I change the third line above to simply localtime(time) there's no problem. The script runs without errors. Anybody have an idea as to what's going on?

not that i have a perl5.6 handy, but this snippet works fine here. Is there a possibility that your code dies somewhere else based on the resulting values of localtime?

Tip: wrap the offending part in an eval { ... } or die $@; block. See what $@ reports for you.

Ah, yes. I'm a boob. The problem was with how the time values were used later on in the code. I was using the data returned by the localtime function to open a file that had a timestamp for its name. By subtracting 86400 seconds, I was trying to open a file that didn't exist. Thanks for snapping me out of my idiocy.
