Looks like a bug, you can report it at connect.microsoft.com. Meanwhile, a workaround is to take advantage of DateTime formatting. Like this:

using System;
using System.Globalization;

class Program {
    static void Main(string[] args) {
        var ci = CultureInfo.GetCultureInfo("ml-IN");
        System.Threading.Thread.CurrentThread.CurrentCulture = ci;
        var ts = new TimeSpan(0, 2, 9);
        var dt = new DateTime(Math.Abs(ts.Ticks));
        Console.WriteLine(dt.ToString("HH:mm:ss"));
        Console.ReadLine();
    }
}

Output:

00.02.09
