I read your post and decided to do an experiment myself and came up with a slight conclusion. When doing a scheduled post through a business page you are able to set the year, month, day, and TIME. When you are doing a scheduled post for a original profile I was only able to set the year, month, and day without a time option. I feel this could be a server issue and not your fault at all. I still have not been able to produce a correct scheduled result along the lines of a how business pages work. I hope this helps and we will have to suffer together it seems!
