Auction Legal Sale Hours. When to show?

[Logan Pourbaix]

There were several properties listed scheduled for auction this morning at my local courthouse. When I arrived at 10am, there was only one property being auctioned off. I did some digging and found out that the other properties were being sold through a different auction company. Upon calling the other companies I discovered that the other properties had been cleared for sale and they would be sold today between the legal sale hours of 10am to 4pm. These different auction companies use one auctioneer for multiple auctions in the area and they would offer me no update as to where this particular sale was listed in the roster. 

My question is relatively simple. Is this common with a lot of auction companies or is it just these one or two in particular? What do people do if the time is not clear, sit at the courthouse all day? Im all about hustling and being patient but I do have other tasks to do throughout my day.
