-> I'd appreciate this feature for a simpler reason: If I move my
-> Subversion repository (for example), ikiwiki changes every post's
-> date of publication to the date of the move. It'd be wonderful if
-> one could specify a date independently of the file's metadata in the
-> repository, just as one can specify a title independently of the
-> filename. —[[cfm]]
+>>> FWIW, for the case where one wants to update a site offline,
+>>> using an ikiwiki instance on a laptop, and include some deffered
+>>> posts in the push, the ad-hoc cron job type approach will be annoying.
+>>> 
+>>> In modern ikiwiki, I guess the way to accomplish this would be to
