Stop links to Jan 2038

/**
 * In some installations category month views for dates in 2038 onwards result in a server error which may have SEO
 * ramifications (as a bot might crawl to these links and encounter a 503).
 *
 * This function is a bit of a string function hatchet job but should resolve this even so. An equivalent to kill links
 * to dates before the Unix epoch could be similarly set up using the equivalent prev_month filter.
