summary:     remove kluge for apparent libc bug that is really a 
valgrind bug

It is a bug only on cygwin   ?

from system time.h

struct tm
{
  int   tm_sec;
  int   tm_min;
  int   tm_hour;
  int   tm_mday;
  int   tm_mon;
  int   tm_year;
  int   tm_wday;
  int   tm_yday;
  int   tm_isdst;
};


from http://www.delorie.com/gnu/docs/glibc/libc_435.html
is seems that tm_gmtoff is a libc BSD extension and not in Posix.
