JodaTime incorrectly converts some time zones on JDK 1.6 about joda-time

[jodastephen]

TimeZone jdkMST = TimeZone.getTimeZone("MST");
TimeZone jdkDenver = TimeZone.getTimeZone("America/Denver");
System.out.println(jdkMST);
jdkMST.setID("America/Denver");
System.out.println(jdkMST);
System.out.println(jdkDenver);
System.out.println(jdkDenver.equals(jdkMST));  // true

Given this code it can be seen that MST and America/Denver in the JDK both have the identical time-zone rules.

The Joda-Time code simply maps "MST" from a TimeZone to "America/Denver" so that the same behaviour is observed for both TimeZone and DateTimeZone when a conversion is made.

Asking for "MST" directly from Joda-Time without going via TimeZone returns what the tzdb defines the ID as, which is without DST

America/Denver is MDT, isn't it?
