This function returns 0, when
tm->tm_hour = 3;
tm->tm_min = 0;
tm->tm_sec = 0;
tm->tm_year=2001;
tm->tm_mon=3;
tm->tm_mday=25;
otherwise it returns correctly tm_gmtoff. (in config.h HAVE_TM_ZONE defined
as 1)

I set TZ (or TimeZone in psql) to undefined or to my local timezone, but it
does not influences on result.
in /etc/ I have symlink "localtime" to /usr/share/zoneinfo/...
Good Luck.
