tm_gmtoff should be 28800 for Etc/GMT+8,
but got -28800,

however, set timezone to Hongkong(which is the same as GMT+8) seems ok.

seems zoneinfo for Etc/GMT+X and Etc/GMT-X are swapped.

below is test code.

#include <time.h>
int main()
{
  struct tm * lt;
  time_t t = time(NULL);
  lt = localtime(&t);
  printf("timezone is %s\n", lt->tm_zone);
  printf("gmtoff is %d\n", lt->tm_gmtoff);
}
