+Summary: DateTime.Parse does not support alternate date separator characters
+DateTime.Parse is unable to parse a date string containing date separator 
+characters other than the date separator of the culture used to parse the 
+for example, the following code fragment works fine on MS.NET :
+DateTime.Parse("01-25-2004", CultureInfo.InvariantInfo);
+even though the date separator character for the invariant culture is '/'.
+Executing the same code on Mono/Linux causes a FormatException as Mono 
+only accepts the date separator of the passed IFormatProvider (in this 
+case the invariant culture).
+see line 899 of DateTime.cs :
+if (!_ParseString (s, 0, dfi.DateSeparator, out num_parsed))
+   return false;
+I guess Mono should not check if s[0] equals dfi.DateSeparator, but it 
+should check whether s[0] is not a letter, not a digit and not equal to 
+dfi.TimeSeparator. All other characters should be allowed as input date 
+The attached class contains the following code :
+and outputs the following on MS.NET :
+25/01/2004 0:00:00
+25/01/2004 0:00:00
+but throws a FormatException on Mono/Linux
+Note : this issue does not reproduce on Mono/Windows at this time, because 
+of bug #54046.
