It would have to be a custom one. One you write. But I believe Tika would pass a file name as one of the parameters, so you just need to use standard Java API to look up the system date. That - of course - assumes that the files you index are on the same filesystem as Solr itself, so it could look it up.
You can find more about the UPRs at: https://cwiki.apache.org/confluence/display/solr/Update+Request+Processors You can find the full list of the URPs at: http://www.solr-start.com/info/update-request-processors/ If you are on the latest Solr 6.4, you would probably want to subclass SimpleUpdateProcessorFactory and follow the implementation example of TemplateUpdateProcessorFactory https://github.com/apache/lucene-solr/blob/releases/lucene-solr/6.4.0/solr/core/src/java/org/apache/solr/update/processor/TemplateUpdateProcessorFactory.java Alternatively, you could implement your URP in Javascript, but I am not sure that has an API to check file dates.
