No. That's fine, because the US is in daylight time right now:

   % env TZ=America/Denver date +%z
   % env TZ=America/Chicago date +%z
   % env TZ=America/New_York date +%z

The value that gets left in the global variable "timezone" is broken,

   % env TZ=America/Denver ./test 
   % env TZ=America/Chicago ./test 
   % env TZ=America/New_York ./test 

Trying some other zones in America/, it looks as if whatever sets it
is honoring DST only for Chicago. Which is strange.

My test.c:

   #include <stdio.h>
   #include <time.h>

   int main(void) {
      time_t t;

      t = time(NULL);
      printf("%ld\n", timezone);
      return 0;

I think another valid question to raise is whether this global
variable needs to continue to be supported...
