I have observed cache dates changing, and going backwards in time. For example, my site was cached with a date of May 8 (on the 9th). Then yesterday, it said "May 7". Today "May 6". This is probably a result of datacenter variance, but it struck me as odd, in light of the reported low Googlebot activity.
