There are three different time zone settings on my machine with the abbreviation CST:

-06:00    QN0600CST   CST        Central Standard Time
-06:00 > QN0600CST2 CST        Central Standard Time
-06:00    QN0600CST3 CST        Central Standard Time

Two of them (QN0600CST and QN0600CST3) have the pre-2007 start and end dates in April and October, while the middle one has what I understand to be the currently legislated start and end of March and November.

Would I be correct in my understanding that QN0600CST2 is the correct value that everyone in the Central Time Zone should be using?
