  Log:
  Split the global timezone structure into two integer fields to
  prevent the compiler from optimizing assignments into byte-copy
  operations which might make access to the individual fields non-atomic.
  
  Use the individual fields throughout, and don't bother locking them with
  Giant: it is no longer needed.
