This will clear console screens idle for more than 15 mins.

    :
    who -u | awk '{
	tty=$2				# basename of tty
	idle=$6				# time idle in "hh:mm"
	if ( tty !~ /^tty[01][0-9]$/ || idle == "." )
	    next			# skip non-console & non-idle terms
	n = split(idle,x,":")
	if ( x[1] * 60 + x[2] > 15 )	# print tty if idle > 15 mins
	    print tty
    }' | while read tty ; do echo "\f" > /dev/$tty ; done

Suitable for running from cron.  Also note that writing to the console
screen will reset that screen's idle time counter.  Also note that this
might need to be run as root if permissions require (e.g. "mssg n" was
run on one of the screens).
