Returns the Twitter status updates for a user in iCal format. The more updates, the longer this will take (and it may take a while!). The result can be imported into Google Calendar or other application that uses the iCal format. Run the Pipe, and right click and copy the link from the "Get as iCal" choice in the "More options" dropdown.
