RSS Feed Time is Incorrect

I am tying to import my Pownce feed into my Tumblelog. Unfortunately it imports them and sets the date to be 6 hours previous to what it should be (ex. 10PM shows as 4PM...). I even tried to show them in Safari and Mail just to make sure it wasn't Tumblr that was messing it up, but it still shows as 6 hours behind time.

It's odd because on my public page it shows the posts as being 2 minutes ago or 3 hours ago which would be the correct times, it's just the RSS feed that doesn't have the correct time in it.

Anyone else notice this and how can it be fixed.

Thanks!
