Jowi pointed out that my RSS feed would behave strangely with NetNewsWire. All my posts register as being 8 hours into the future. If I posted something at 1pm, it shows up 9-ish on the reader.
I’m using the Atom 2.0 spec and while my time-stamp syntax is correct – the reader doesn’t seem to handle it correctly. This is really irritating because is only evident with my Atom 2.0 RSS feed – the pages in the site itself still display the right local time.
