printout time in a specified timezone

I can printout time in UTC and local time like this:

  time_t now;
  struct tm  ts, tm;
  char buf[80];
  now = time(NULL);
  ts = *gmtime(&now);
  tm = *localtime(&now);
  strftime(buf, sizeof(buf), "%a %Y-%m-%d %H:%M:%S %Z", &ts);
  printf("%s\n", buf);
  strftime(buf, sizeof(buf), "%a %Y-%m-%d %H:%M:%S %Z", &tm);
  printf("%s\n", buf);

But how do I printout time in a specified timezone that is different than UTC or my current timezone? Also, would it be OS/distro dependent?

You can use the approach documented here How can I set the time zone before calling strftime?, so use setenv and tzset before calling strftime:

setenv("TZ", "PST8PDT", 1);
tzset();
mtt = time(NULL);
mt = localtime(&mtt);
strftime(ftime,sizeof(ftime),"%Z %H%M",mt);
