The API documentation does not clearly list the date format for obtaining direct_messages sent to a user (within the specified date/ time window). I am using RFC 1123/822 format but do not get any messages sent with in the specified date/time window:
For Example: direct_messages.xml?since=".urlencode("Sun, 26 Oct 2008 22:00:00 EST") (does not return any messages or errors.) What is the correct date/time format? Has anyone used this successfully? Thanks
