Ugh. I had to deparse it to see the forest for all those parens (hacker's version is even worse). What purpose does reversing an already random string serve? It doesn't contribute any randomness. Not to mention you're calling reverse in list context but with only one parameter, so effectively it's not even doing anything at all. 
#!/usr/bin/perl -w
use strict;
use English '-no_match_vars';

my $sum = 0;
$sum += $_ for localtime;

print substr(crypt($sum * $UID / $EGID, rand $PID), 2, 9);

Generally it seems like you're just trying to throw as much "random stuff" into the pile as possible - but it's not really contributing anything. For high quality random data rendered as a typeable string I'd just dump a bunch of bytes from /dev/urandom and uu- or base64-encode them.

Makeshifts last the longest.
