(see [[!iki tips/howto_avoid_flooding_aggregators]]).
+* updated
+
+ Specifies a fake modification time for a page, to be output into RSS and
+ Atom feeds. This is useful to avoid flooding aggregators that sort by
+ modification time, like Planet: for instance, when editing an old blog post
+ to add tags, you could set `updated` to be one second later than the original
+ value. The date/time can be given in any format that
+ [[!cpan TimeDate]] can understand, just like the `date` field.
