Comment:
use_doc_date and ISO_8601:



use_doc_date works properly, as it only need to get the DATE part (http://dublincore.org/documents/dces/); however, when the modification time is shown through htsearch, if the format specifies a time part (hours, minutes, seconds and - worse - a timezone!) the midnight of that day is taken and wrong information is shown.



When having a deeper look at this, we came across the W3C standard for date time specifications (http://www.w3.org/TR/1998/NOTE-datetime-19980827) 

I discovered (too late, I know!) that date times should be specified using the complete ISO 8601 format, which is different from the ones that the HtDateTime actually handles. 



In particular, here is their format:

YYYY-MM-DDThh:mm:ssTZD

for instance: 1997-07-16T19:20:30:+01:00



Should we implement this or not?



Also, strptime can't handle timezones, which makes modification time not to work properly.



However, use_doc_date works fine (it overrides the server date) although - I guess - we could write in the documentation that if this is enabled times in the htsearch output should be disabled.

Comment:
date_factor: with the current weight formula, documents made earlier than 2000 get a negative score. In some cases documents disappear from the results, which is something - I guess - we don't want to happen. I suggest a revision of this formula, currently:



date_score = date_factor * ((document_date * 10 / now) - 9)



However, the factor works.
