The problem with your test program is that tm is uninitialized, which
strptime does not alter (since there is no zone information in the input)
and which causes strftime to bomb. Using memset(&tm, 0, sizeof(tm))
causes %z to be +0000 (wrong) and %Z to be "EST" (correct). So that's
not a feasible approach.
Here's a demo program that does work:
#include <stdio.h>
#include <string.h>
#include <time.h>
int main() {
struct tm * tm;
char buf[1000];
time_t t;
buf[0] = 0;
t = time(NULL);
tm = localtime(&t);
strptime("2008-11-12 18:31:01", "%Y-%m-%d %H:%M:%S", tm);
strftime(buf, sizeof(buf), "%d %b %Y %H:%M %z %Z", tm);
puts(buf);
return 0;
}
However, this doesn't really solve your problem, because it sets
the offset and tzname to the current values, not to the values in
effect at the time.
I admit I don't know how to make progress here. Let me think on it.
