I can't make heads or tails of it. I think it's just odd to cache a page, and not display that cache until 5 days later. I only noticed it about a month ago, but if you have seen it for a year, it must not be anything new. Everything is just so slow on G right now, and I haven't had a deep crawl since January 9. The pages are getting cached very intermittently, a couple of pages are crawled here and there, but not a deep spidering.
I have new pages that were added mid January, not cached until February 9. That is still the current cache date showing.
