Do you respect the date_modified field?

[Dan Langille]

At present, FreshPorts deletes all VuXML information each time a 
commit to ~/ports/security/vuxml/vuln.xml occurs.  To reduce database 
churn, I'm now looking at optimizing this process.

I expect the answer to my question to be yes, but do not want to rely 
upon only my expectation.  Do you respect the date_modified field?

I ask for reasons of keeping things simple.  FreshPorts inserts each 
vuln into a table.  Is it sufficient for FreshPorts to compare the 
last_modified field as supplied in vuln.xml to determine whether or 
not it should update its information?

Thanks
