Brion Vibber 6b134ae4c7 Dropped deprecated timestamp-based 'since' parameter for all API methods. When it sneaks in it can cause some very slow queries due to mismatches with the indexing.
Twitter removed 'since' support some time ago, and we've already removed it from the public timeline, so it shouldn't be missed.
