Just don't poll between 8am and midnight. A crontab entry like:
*/5 8-23 * * * /usr/bin/mrtg.pl var/lib/mrtg/mrtg.cfg
Would do the trick.
If you want to skip weekends too, it would be:
*/5 8-23 * * 1-5 /usr/bin/mrtg.pl var/lib/mrtg/mrtg.cfg
As long as you have options[]: unknownaszero you should be fine with no
interpolation. There might be some funkiness at 8:00am, but it is unlikely
to be statistically significant.
