Ah, now we're getting there :-)

# grep "^C " /var/db/sup/src-all/checkouts.cvs:. | awk '{print $7}' | 
sed 's/^9/199/' | sort -u | tail -n 10

gives me the ten latest commit dates. It would be cool to somehow 
connect this with the tinderboxes, to mark date intervals with broken 
builds. But that's another project...

Thanks to everyone for your kind help!
