TimePicker

[h0545772386]

Describe the bug

The value of SelectedDateTime of the TimePicker control is double somehow and exception falls when binding with a converter.

I save my datetime as long number yyyyMMddHHmm and convert it for display.

here is my details:

version installed:

<package id="MahApps.Metro" version="2.4.10" targetFramework="net472" />

window xmlns:

 xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"

window coverter definition:

 <mah:MetroWindow.Resources>
     <local:TimeConverter x:Key="TMCNV" />
     <local:DateTimeConverter x:Key="DTCNV" />
     <local:StatConverter x:Key="STCNV" />
 </mah:MetroWindow.Resources>

control at XAML:

   <mah:TimePicker x:Name="timePopup"
                   Grid.Row="3"
                   Grid.Column="1"
                   Margin="3"
                   HorizontalAlignment="Left"
                   Width="150"
                   Culture="he-IL"
                   SelectedTimeFormat="Short"
                   SelectedDateTimeChanged="timePopup_SelectedDateTimeChanged"
                   SelectedDateTime="{Binding PHdr.TimePopup,Mode=TwoWay,Converter={StaticResource TMCNV}}" />

converter class code

internal class TimeConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if ((long)value == 0)
                return new DateTime(1973, 02, 07, 0, 0, 0);
            long d1 = long.Parse(DateTime.Today.ToString("yyyyMMddHHmm"));
            d1 =  d1 + (long)value;
            DateTime d2 = DateTime.Today;
            try
            {
                d2= DateTime.ParseExact(d1.ToString(), "yyyyMMddHHmm", CultureInfo.InvariantCulture);
            }
            catch { 
            }
            return d2;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (value == null)
                return (long)0;
            return long.Parse(((DateTime)value).ToString("yyyyMMddHHmm"));
        }
    }
}

to trigger the bug use the code and try to change the Time then it will appear
