Possible error with date_timestamp:ago

[odeclas]

Not sure if this is getFeed or output filter that's at fault, but using the code from the Addons doc you get a display that says the tweet was posted 40 years 8 months ago, irrespective of when it was actually posted (using :date=%c seems to indicate the string is the right date, so I might be filing this in the wrong place, sorry).
