It IS simple! (or should be.) - What exactly are you doing?
And what exactly isn't working? ( and do you have the right
options turned on on your server, and is you script in a
directory where the server can access + execute it ? )

This is not linked into anywhere from our home page -
this was just my first try at a python cgi script.

You can look at the output by connecting to URL:

Not a particularly neat or orderly program - I was trying to
see if I understood the protocol ( and after 3 or 4 tries, I
think I finally do! ;-)

This SHOULD give (my) local-time,
( This is where I ran into the tzset() problem, although I do
believe that time should be available from a CGI environment
variable. )
cal output with today's data in <B>old<\B> and a fortune cookie
message. ( And it does do all that on *my* Mosaic/X11, at least. )
