r.2334 build on the nightlies site appears to be a copy of r.2311

Just went to download the latest nightly build r.2334. When it downloads it downloads as r.2311.7z. Comparing the modify date on on nightly.exe in \bin in the zip file and in my install directory for r.2311 shows that they carry the identical date time stamp, 7 November 2009 7:18AM. Is this truly supposed to be r.2334 or is there a mix up somewhere, most likely between my seat and my keyboard.

Keith
