Bug 621408

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.99 Safari/533.4

When trying to find a TimeZoneInfo by Id, you can't use the local TimeZoneInfo's Id.

TimeZoneInfo.Local.Id results in "Local"

"Local" is not a valid Id for any TimeZoneInfo in TimeZoneInfo.GetSystemTimeZones()

Reproducible: Always

Steps to Reproduce:
1. $> csharp
2. TimeZoneInfo.FindSystemTimeZoneById(TimeZoneInfo.Local.Id);
Actual Results:  
System.TimeZoneNotFoundException: Exception of type 'System.TimeZoneNotFoundException' was thrown.
  at System.TimeZoneInfo.FindSystemTimeZoneByFileName (System.String id, System.String filepath) [0x00000] in <filename unknown>:0 
  at System.TimeZoneInfo.FindSystemTimeZoneById (System.String id) [0x00000] in <filename unknown>:0 
  at Class6.Host (System.Object& $retval) [0x00000] in <filename unknown>:0 
  at Mono.CSharp.Evaluator.Evaluate (System.String input, System.Object& result, System.Boolean& result_set) [0x00000] in <filename unknown>:0 
  at Mono.CSharpShell.Evaluate (System.String input) [0x00000] in <filename unknown>:0 


Expected Results:  
A TimeZoneInfo representing the current time zone should be returned.
