sys_tz can be set with settimeofday().

Try this C program:

====== BEGIN settz.c ======
#include <sys/time.h>
#include <unistd.h>

int main( int argc, char *argv[] )
{
        struct timezone tz;
        tz.tz_minuteswest = -10 * 60; /* or whatever */
        tz.tz_dsttime = 0;
        settimeofday( NULL, &tz );
}
====== END settz.c ======

And look at the man page for settimeofday!
