Based on the atom spec, I think ikiwiki is using atom:updated correctly,
since it sets it to the mtime of the file.
The relevant field that planet should be looking at if it wants
a static publication date is atom:published. Ikiwiki sets that to the initial
page creation date, and never changes it.
Here is an example from my latest blog entry, which I posted and then
edited. (But planet debian uses my rss feed, and seem to be happy with
what ikiwiki does there.)

I suspect that planet is doing the wrong thing..
Relevant spec:
4.2.15 The "atom:updated" Element
The "atom:updated" element is a Date construct indicating the most recent
instant in time when an entry or feed was modified in a way the publisher
considers significant. Therefore, not all modifications necessarily result in
a changed atom:updated value.
atomUpdated = element atom:updated { atomDateConstruct}
Publishers MAY change the value of this element over time.
4.2.9 The "atom:published" Element
The "atom:published" element is a Date construct indicating an instant in time
associated with an event early in the life cycle of the entry.
atomPublished = element atom:published { atomDateConstruct}
Typically, atom:published will be associated with the initial creation or
first availability of the resource.
4.2.6.1 Comparing atom:id
Instances of atom:id elements can be compared to determine whether an
entry or feed is the same as one seen before. [...]
