Hello, I see your answer to this error: ERROR: Ran out of valid boundary conditions in file wrfbdy_d01. At present, I have encountered the same question. My start date is 2010-11-14-00-00-00 and end date is 2010-11-22-18-00-00. According to your answer, I set run days is 8 and run hours is 18. But my wrfbdy's end date is still 2010-11-22-12-00-00.
