How about the following:
#!/bin/sh
# wall_uptime.sh
sleep 30
echo "Uptime is 30 minutes" | wall
and in your rc.local:
/path/to/wall_uptime.sh &

We used to put something like this in /etc/rc.local but that is deprecated,
these days the best way to start your scripts will be /usr/local/etc/rc.d
mind the syntax it has to be in then, though, you''l need to provide at
least a 'start' and 'stop' option. For a starting point, just copy one which
is already there. Notice that scripts you put in there will need to have
a .sh extension to make them run.

From man wall:
DESCRIPTION
Wall displays the contents of file or, by default, its standard input, on
the terminals of all currently logged in users.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There won't be any messages on other ttys, just for the users who are logged
in at that moment.
