Thanks for the reply. I did submit the issue to Google through that same link around a month ago. I got an automated response, thanking me for submitting the issue.  Nothing further as of today.

To reply in order:

1. We have no “hours” issues related to our two locations that I can see, and if we did I would suspect that Google would get the hours off by an hour.  (One location closes at 5pm, the other at 6pm.)

2. We cleaned up our duplicate places page issue probably 2.5 years ago, and even then, there were no hours on the duplicate page to mess things up.

3. I agree with you that Google has to grab the data from somewhere, so when I went out to look for third party citations, I used the Moz “Get Listed” tool, and also did some refined Google searches to see where the citation might show up.  No luck so far. All those “free listing” pages come up with the proper hours as well.

4. No "split day" issue that I can see.  I can't think that our Saturday hours are messing this up, but that is where we have our 1 pm closing time.

Here’s another twist.  When I submitted the issue to Google, I also pointed out that our “Plus or Places” page does not list our hours when that page comes up in the SERP’s. I don’t have any settings checked off that would hide those hours.

When doing the following search on Google "Ticket King Milwaukee hours" we see the wrong hours displayed at the top of the page. Just to the left of our places page, you will see "Tuesday hours 8:30-1:00 pm." That 1 pm closing comes up for every weekday, even though we are open until 6 pm weekdays, and 3 pm on Saturdays. I have checked the hours listed on our G+ page, our "Places for Business" page, our "about us" page on our website, and can't find where they are getting this incorrect data. I even went out and checked most of the "List your business" sites that I have registered with.
I have submitted this to Google, but have not heard back. Does anyone have any ideas as to how I can fix this, or at least find out where this bad data is coming from? I did find a company blog post from 2010 that listed our ours in a somewhat confusing way, but it was still correct. (I have since fixed that old post.)
