Wrong date during Backtesting

Hello!

I have the following issue:

I set up a filter on time to prevent the robot from trading during specific hours:

        [Parameter("UTC Trade Start", DefaultValue = 22.0)]
        public double TimeStart { get; set; }
        [Parameter("UTC Trade Stop", DefaultValue = 8.0)]
        public double TimeStop { get; set; }

            startTime = Server.Time.Date.AddHours(TimeStart);
            endTime = Server.Time.Date.AddHours(TimeStop);
            
            
            bool tradeTime = Server.Time >= startTime && Server.Time <= endTime;
            if (!tradeTime)
            {
                Print("Start time, server time, finish time: {0},{1},{2}", startTime, Server.Time, endTime);
                return;
            }
            
During backtests, I noticed that both variables of start time and stop time are changing correctly while server time is using the date which is set up as a date to finish backtest.

16/10/2014 21:44:48.086 | Start time, server time, finish time: 08.09.2014 22:00:00,16.10.2014 17:44:48,08.09.2014 8:00:00

17/10/2014 03:54:56.440 | Backtesting finished

What should I use instead of Server.Time during backtesting to enable it to work properly?
