DateTime.Now.Tostring() - weird results

Question

I'm using Mono on the Raspberry Pi (running Raspbmc). Most things (amazingly!) simply work, however there's one piece of code that is acting weird.

Using the csharp C# "shell", I get this (same results for the compiled counterpart):

csharp> DateTime.Now.ToString();
"00/735023/0001 23:05:56"

csharp> DateTime.Now.ToString("dd"); //get day numeral
"735023"

csharp> DateTime.Now.ToString("MMMM"); //get month name
System.ArgumentOutOfRangeException: Argument is out of range.
  at System.Globalization.DateTimeFormatInfo.GetMonthName (Int32 month) 
  [...]

...However, accessing the separate properties works:

csharp> DateTime.Now.Day.ToString();
"4"

csharp> DateTime.Now.Month.ToString();
"6"

csharp> DateTime.Now.Year.ToString();
"2013"

Any idea what's going on, or at least where I should submit a bug?

FWIW: This is what I'm running

pi@raspbmc:~$ mono -V

Nevermind... looking into it further and it doesn't match up as a date serial. Ignore me — emd, Jun 04 '13 at 20:20
It may be a known issue? http://raspberrypi.stackexchange.com/questions/5094/how-bad-are-the-mono-errors-at-the-moment-eg-datetime-issues — emd, Jun 04 '13 at 20:21
Perhaps take a look at this post seems to be similar issue. http://stackoverflow.com/questions/12597317/how-to-format-datetime-to-local-users-locale-in-short-time-format-using-monotouc — Bearcat9425, Jun 04 '13 at 20:21
@emd yep, you are correct. The answer to *that* question points to the same Mono bug that's described in the accepted answer. — Cristian Diaconescu, Jun 05 '13 at 10:14

There's relevant bug reported: https://bugzilla.xamarin.com/show_bug.cgi?id=7938. Reason: using hardfp instead of softfp floating point ABI which is incompatible with Mono 2.10. There are some patches coming to support the hardfp in Mono, but nothing yet mainline.

Thanks for the link to the bug! It's exactly what I've been experiencing. Unfortunately, the bug was opened 9 months ago (at the time of writing) and the comments are not encouraging: "*the patch is linked in comment#3. AFAIK it's not going to be included upstream because of licensing conflicts.*" – Cristian Diaconescu Jun 05 '13 at 10:17
