DateTime.ToString in Mono return invalid date (“00/734718/0001 01:41:38”)

Question

I am trying to get mono (Debian 2.10.8.1-5) to run properly on my raspberry pi with the raspbian distro (\"Debian GNU/Linux wheezy/sid\"). I have installed mono with apt-get

Answer 1

I can't reproduce your issue on Windows (don't have raspberry, but your subject says Mono).

I copied and pasted your exact source for Main() into a new Mono console app (Mono 2.6.1), added a single line (Console.ReadLine();), and ran it:

using System;

namespace TestDateTimeNow
{

  class MainClass
  {
    public static void Main (string[] args)
    {
        DateTime now = DateTime.Now;
        Console.WriteLine("Year: " + now.Year);
        Console.WriteLine("Month: " + now.Month);
        Console.WriteLine("Day: " + now.Day);
        Console.WriteLine("DayOfWeek: " + now.DayOfWeek);
        Console.WriteLine("DateTime.Now: " + DateTime.Now);
        Console.WriteLine(DateTime.Now.ToString("yyyy-MM-dd"));
        Console.ReadLine();
    }
  }
}

I get the output below:
