The only way I see for an external user is to load the details page for every tile (http://tah.openstreetmap.org/Browse/details/tile/12/x/y/) and get the "last modified" date. But I don't think that would be very nice to the tah server. I have always felt that there should be a process that enters the oldest tiles in the queue (with low priority) so that every tile will get rerendered with new rules every once in a while. That said: there are still wrong rules or renderers that use out-of-date rules. I believe the issue of large names of waterfeatures and landfeatures in lower zoomlevels has surfaced before, but it is still an issue. See tile 12, 2111, 1353 at <http://informationfreeway.org/?lat=51.957&lon=5.570&zoom=12&layers=B0000F000F> where the text "Neder Rijn" (and "Lingekanaal" in a neigbouring tile) should not be there in zoom 12 and gets smaller in zoom 13 and 14 and gets larger again from zoom 15. I have requested rerenders of other tiles to see if it is a current problem.
