What is the type of subtitle (.srt) time frame?

I am working on C# application which will read .srt file and show it on screen.

File format is simply like this;

1   00:00:06,000    00:00:07,400    Enjoy the movie! 
2   00:00:07,500    00:00:09,500    Hi, my name is Mary
3   00:00:22,000    00:00:25,000    Hello my name is John.

I am using a timer which is ticking every 100 milliseconds and on every single tick I want to check if value is between start and end. In this case first will be between 00:00:06,000 and 00:00:07,400. But I am not sure what value I should use. I tried to parse it to DateTime but it did not convert.

Is there any idea?

Use TimeSpan. Here the simple Console Project to show subtitles on the correct time

    class Program
    {
    private static Queue<Subtitle> _subtitles;

    private static Subtitle _activeSubtitle;

    private static TimeSpan _currentTime = new TimeSpan();

    static void Main(string[] args)
    {
        _subtitles = new Queue<Subtitle>();

        Subtitle title1 = new Subtitle()
                              {
                                  StartTime = TimeSpan.Parse("00:00:06,000"),
                                  EndTime =  TimeSpan.Parse("00:00:07,400"),
                                  Text = "Enjoy the movie!"
                              };

        Subtitle title2 = new Subtitle()
                              {
                                  StartTime = TimeSpan.Parse("00:00:07,500"),
                                  EndTime =  TimeSpan.Parse("00:00:09,500"),
                                  Text = "Hi, my name is Mary"
                              };

        Subtitle title3 = new Subtitle()
                              {
                                  StartTime = TimeSpan.Parse("00:00:22,000"),
                                  EndTime =  TimeSpan.Parse("00:00:25,000"),
                                  Text = "Hello my name is John."
                              };

        _subtitles.Enqueue(title1);
        _subtitles.Enqueue(title2);
        _subtitles.Enqueue(title3);

        Timer timer = new Timer(ShowSubtitles, null, 0, 100);

        while (_currentTime <= new TimeSpan(0, 0, 0, 30))
        {

        }
        Console.WriteLine("End");
    }

    private static void ShowSubtitles(object state)
    {

        if (_activeSubtitle == null && _subtitles.Count > 0)
            _activeSubtitle = _subtitles.Dequeue();
        Console.WriteLine(_currentTime);

        if (_activeSubtitle != null)
        {


            if (_currentTime >= _activeSubtitle.StartTime && _currentTime <= _activeSubtitle.EndTime)
                Console.WriteLine("\t{0}", _activeSubtitle.Text);

            if (_currentTime >= _activeSubtitle.EndTime)
                _activeSubtitle = null;
        }
        _currentTime = _currentTime.Add(new TimeSpan(0, 0, 0, 0, 100));

    }
}

internal class Subtitle
{
    public TimeSpan StartTime { get; set; }
    public TimeSpan EndTime { get; set; }
    public string Text { get; set; }
}

You can use either DateTime or TimeSpan but you need to supply correct format to ParseExact function.
