Description Paul Donovan 2012-02-19 19:13:29 UTC
The output of converting a DateTime object to a string using the "g" formatter is incorrect when using the Australian locale on the iPhone. The 'M' at the end of PM is missing.

Using MonoTouch 5.2.4 and the iOS 5.0 SDK, targeting iOS 4.3 on the iPhone simulator, if you go to Settings->General->International->Region Format and choose Australia, the   output of the DateTime to string is incorrect when running the following code:

DateTime dt = new DateTime(2012, 12, 30, 23, 30, 15);
Console.WriteLine(String.Format ("Time is {0:g}", dt));

Expected results:

Time is 30/12/2012 11:30 PM

Actual results:

Time is 30/12/2012 11:30 P

This doesn't appear to be something as simple as a string buffer being the wrong length, as when the locale is US it's able to output a string that's as long as the required Australian output:

Time is 12/30/2012 11:30 PM

This can also be reproduced with a simple console application:

using System;
using System.Diagnostics;
using System.Threading;
using System.Globalization;

class gdb {
  static void Main(string[] args) {
    var ci = new CultureInfo ("en-AU");
    Thread.CurrentThread.CurrentCulture = ci;
    Thread.CurrentThread.CurrentUICulture = ci;
    Console.WriteLine (ci.DisplayName);
    Console.WriteLine (string.Format ("Time is {0:g}", new DateTime(2012, 12, 30, 23, 30, 15)));
  }  
}
