 As far as I can tell, a zero TTL (number after RFC) can only
 happen here if your default_ttl parameter is set to zero, OR
 if there is clock-skew between the varnish machine and the
 backend machine.

 Make sure both machines run NTP.

 You can test that they agree by running
   ntpdate -d $backend
 on the varnish machine (or vice versa).


But would this matter since he is resetting the obj.ttl to 1 day in  
vcl_fetch?

Yes, the RFC2616 based TTL is calculated before vcl_fetch is run.

Is this truly all you have in vcl_recv?  This will mean that any  
cookied requests will get passed.  Is this intentional?

No, this is not a production setup. My problem is not that I cache too 
much, but the opposite.

And yep, I know about the cookie issue:

Sorry, I'm confused.  Maybe I'm misunderstanding what you're saying  
here, but the cookie issue will mean that you will cache too little,  
not too much.
