I think he meant to use exactly "D" as in the US Military zone name,
not wanting a DST flag.

Personally I'd prefer to the zone "abbreviations" (for all zones) were
set to something like the function in the attached program prints (using
tm_gmtoff for the zone - or what its value would be if it existed, in cases
where it does not.)

#include <stdlib.h>
#include <stdio.h>

#define Abs(n)	(n ? abs(n) : 1)

void
pr_gmtoff(long tm_gmtoff)
{
	int n;

	n = -tm_gmtoff / 60;
	printf("%+5.4d", n/Abs(n) * ((abs(n)/60)*100 + (abs(n)%60)));
}

#ifdef TEST

int
main(int c, char **v)
{
	int i;
	long gmtoff;

	for (i = 1; i < c; i++) {
		gmtoff = atol(v[i]);
		printf("From %6s: <", v[i]);
		pr_gmtoff(gmtoff);
		printf(">\n");
	}
	exit(0);
}
