Hi,

Can anyone confirm that if I want to use an alternative HTML metadata 
element (in this case the Dublin Core Date.modified element) as the 
swishlastmodified property for an indexed  document (via 
ProperyNameAlias) that the only encoding scheme that will work is 
'seconds since the UNIX epoch' ?

At present all the docs to be indexed contain DC date elements encoded 
via the (default) W3C-DTF scheme. Also I dont think that the DC allows 
any other format for Date elements . I certainly have never seen anyone 
generating DC Date elements with Unix epoch time-stamps.

Indexing said documents generate this error (and empty 
swishlastmodified properties) :

Warning: EncodeProperty - Invalid char '-' found in string '2005-06-30 
09:39:12 +1000'
Warning: Failed to add property 'swishlastmodified' in file 
'http://myserver.mydomain/mydocument'

Is there a recommended way to extend swish-e cleanly to do the 
conversion or do I have to modify core swish-e code to enable detection 
of W3C-DTF date metadata  and convert it to unix epoch format ?
Or would it be better idea to extend the spider to preconvert the 
DC.Date.modified values before passing to swish-e ?

If I do need to modify swish-e, is it this facility something that 
would be able to be folded back in to the main code base, rather that 
me having to maintain a forked version ?
