Hi,

Hudson is great software, but there's one thing that has been annoying me for a
while: old build entries kept showing as new in my feed reader for the rssFailed
and rssAll feeds.

I investigated recently and it turns out that ids that change are the cause of
the problem. For example, after several updates there were 3 entries with the
following ids in my feed reader:

tag:hudson.dev.java.net,2008:<projectName>:2008-01-27_03-07-23
tag:hudson.dev.java.net,2008:<projectName>:2008-01-27_03-37-59
tag:hudson.dev.java.net,2008:<projectName>:2008-01-01_02-08-01

As can be seen, the date appended to the id is different in each case. However,
the link is the same for all 3 entries (indicating that it's the same build).
The published date matches one of the 3.

My first thought is that something is causing the published date to change,
which in turns causes the id to change. Any idea what could cause that? It seems
completely random to me so far.
