Eww. The time functions we have to play with _really_ suck, don't they?
How about this...

tm_gmtoff is not available everywhere - POSIX doesn't even mention it (BSD?).

Oh btw, when we are about sucking time functions: the %s and %z strftime-
sequences used further down are also non-standard (POSIX has no %s, old
libc has neither %s nor %z).

A possible workaround:

void make_datestamp(char *buf)
{
	time_t now;
	struct tm *tm;
	int tz;

	time(&now);

	tm = localtime(&now); /* get timezone and tm_isdst */
	tz = -timezone / 60;
	if (tm->tm_isdst > 0)
		tz += 60;

	sprintf(buf, "%lu %+05d", now, tz/60*100+tz%60);
}

That *should* work on any POSIX system but who knows ...
