It has been bothering me that my rss aggregator is displaying the time that it loads my posts, and not the time that I wrote them. So I decided to fix this.
The problem was that the rss 2.0 spec states that the date should be in GMT, while pLog was printing it out in the local time zone. This diff, fixes this problem in the 1.0.2 version of pLog. This also has been added to this bug.
Update: I have checked this in to the 1.0.2 tree.
