How to display opening times?

Question

I'm trying to show intervals of working hours/days it's should look like this:

_{(source: clip2net.com )}

I have table where I'm storing day number, open time and closing time for each day

_{(source: clip2net.com )}

Then I created query=>

var groups = from s in this.OpenTimes
orderby s.Day
group s by new { s.Till, s.Start } into gr
select new
{
    Time = gr.Key.Start + "-" + gr.Key.Till,
    Days = this.OpenTimes
        .Where(o => o.Start == gr.Key.Start && o.Till == gr.Key.Till)
        .OrderBy(d => d.Day).Select(d => d.Day).ToArray()
};

This query provides all grouped time intervals and days that included to this time-range But I faced with problem - I created second half that representing this groups, but it's not working properly. Maybe somebody could explain to me needed point of vision or this basic logic of showing opening times.

Thanks in advice...

Next approach works for me:

result screen

  public string OpeningTimesString
      {
         get
         {
            if (!this.OpeningTimes.IsLoaded)
               this.OpeningTimes.Load();
            var groups = (from s in this.OpeningTimes
                       orderby s.Day, s.Start, s.Stop
                       group s by new { Stop = formatTime(s.Stop), Start = formatTime(s.Start), s.Day } into gr
                       select new
                       {
                          Time = gr.Key.Start + "-" + gr.Key.Stop,
                          Day = gr.Key.Day
                       }).ToList();
            string result = "";
            int tmp = 1;
            for (int i = 0; i < groups.Count(); i++)
            {


               //One one = new One();
               bool exit = false;
               tmp = i;
               while (exit == false)
               {
                  if (i + 1 < groups.Count && groups[i].Time.Equals(groups[i + 1].Time))
                  {
                     i++;
                  }
                  else
                  {
                     if (tmp != i)
                        result += (NormalDayOfWeek)(groups[tmp].Day - 1) + "-" + (NormalDayOfWeek)(groups[i].Day - 1) + " : " + groups[i].Time + "<br />";
                     else
                        result += (NormalDayOfWeek)(groups[i].Day - 1) + " : " + groups[i].Time + "<br />";
                     exit = true;
                  }
               }
            }

            if (result.IsNotNull())
               return result;
            else
               return "[%Not yet defined]";
         }
      }
