I thought (maybe I misread tzset()) that tzset() remembers if it's
already been called or not, and returns without doing anything
if it has previously run:

static void
internal_function
tzset_internal (always, explicit)
     int always;
     int explicit;
{
...

  if (is_initialized && !always)
    return;
  is_initialized = 1;

Ah... except that __tzset() calls it with "always == 1".

No idea why.

Which begs the question: why isn't tzset() $%^&* idempotent?
