That doesn't work for BSD.  There is no such thing as TZ.  Instead,
localtime() in ctime.c needs the following modification:

struct tm *
localtime(tim)
long *tim;
{
...
	daylbegin = 119;	/* last Sun in Apr */
	daylend = 303;		/* Last Sun in Oct */
	if (ct->tm_year==74 || ct->tm_year==75) {
		daylbegin = daytab[ct->tm_year-74].daylb;
		daylend = daytab[ct->tm_year-74].dayle;
	}
	if (ct->tm_year >= 87)			<==== add this
		daylbegin = 96;			<==== add this
...

Anything and everything that uses ctime() needs to be recompiled.
