> Among other fields, the more plugin for Nutch 2.x provides a "last modified" and "date"
field for the Solr index. The "last modified" field is the last modified date from the http
headers if available, if not available it is left empty. Currently, the "date" field is the
same as the "last modified" field unless that field is empty in which case getFetchTime is
used as a fall back. I think getFetchTime is not a good fall back as it is the next fetch
time and often a month or more in the future which doesn't make sense for the date field.
Users do not expect webpages/documents with future dates. A more sensible fallback would be
current date at the time it is indexed. 
> This is possible by simply changing line 97 of https://svn.apache.org/repos/asf/nutch/branches/2.x/src/plugin/index-more/src/java/org/apache/nutch/indexer/more/MoreIndexingFilter.java
from
> time = page.getFetchTime(); // use fetch time
> to
> time = new Date().getTime();
> Users interested in the getFetchTime value can still get it from the "tstamp" field.
