Bill Gathen was the first person to answer the
problem correctly, @ around 11:00 or so monday morning.

The 'two or three words' I was looking for were some
combination of 'tcp socket client datetime', so Bill gets
the prize.
Joel Muelenberg answered the problem correctly about
an hour later, and David Hoppe at 5:30PM.
Originally, $org was "daytime(13)", but I changed it to
just 13 because that works, too. So, some of the $org=~s//g
type statements lost all meaning, but it still worked. ;-)
Of course, since the {print} statement was the last
statement before the end of a structure block, the semi-colon
isn't needed, and it works just fine without it. (Learning
Perl, 2nd ed, page 5, little asterisk at the bottom of the
page.) But it sure was a nice red herring ...
I hope this was a good lead-up to our November discussion
of socket programming .... oh, and I call the power reference
next month. ;-)
