need help setting a specific day and time to close trades .... i.e. Friday near market close

I'm using this to try to close all positions on Friday near the close...

but it is not working...

           System.DayOfWeek today = System.DateTime.Today.DayOfWeek;

            if (Server.Time.DayOfWeek == DayOfWeek.Friday && reSet == 0 && reSetGo == 1)
            {
                reSetTime = Server.Time.AddHours(22);

                if (Server.Time > reSetTime)
                {
                    reSet = 1;
                    foreach (var position in Positions)
                    {
                        ClosePosition(position);
                    }
                }
            }

When I use this:  Print("reSetTime = {0}", reSetTime);

I see this: reSetTime = 1/1/0001 12:00:00 AM

How can I do this?

Thanks!
