There is no current time offset stored in a control block, and no need to "do that automatically" semiannually. Rather, they embed a function which takes as an argument a UTC timestamp and returns as a result the corresponding local timestamp. This works equally for historic timestamps. During the summer, the function can be called with a UTC value from the previous winter and it will correctly return the corresponding local time. In the U.S.A. the last time the function was updated was in 2006, as a consequence of legislative change. The updated function still gives correct results for times before 2006 as well as after.
