One way to do what you want is to put your time-sensitive rules in a
separate set:

 ipfw add 500 set 1 reset ip from any to any dst-port 554 // block realaudio streams

Then use cron to enable/disable them during your timerange:

 0 8 * * * root ipfw set enable 1
 0 18 * * * root ipfw set disable 1

You can run "ipfw -S list" to see which sets are active at any time. 
It would be nice to have this built into ipfw, though.
