The belize entry does not have a current rule and I take this to mean
that they currently do not observe daylight savings time.

The problem is, what is the value that is to be substituted into C%sT
if there is no rule?

Should the formatted name of the time zone be "CT" or "CST"?  If it is
supposed to be CST, how are you to know this?

I am using Belize as an example, there are several timezones that have
this same problem:
	Asia/Yerevan
	America/Buenos_Aires
	America/Barbados
	America/Belize
	Asia/Harbin
	America/Bogota
	America/Costa_Rica
	Africa/Accra
	America/Guatemala
	America/Tegucigalpa
	Asia/Tehran
	Asia/Seoul
	Asia/Macao
	America/Lima
	Asia/Manila
	Africa/Khartoum
	Africa/Freetown
	America/El_Salvador
	Africa/Tunis
	Asia/Taipei
	America/Montevideo
	Pacific/Efate
	
As an extreme example of this problem is exhibited by 
	Africa/Accra
	Africa/Freetown
