zsh doesn't check for localtime() failure in datetime.c:

    t = localtime(&secs);
    bufsize = strlen(argv[0]) * 8;
    buffer = zalloc(bufsize);

    for (x=0; x < 4; x++) {
        if (ztrftime(buffer, bufsize, argv[0], t) >= 0)
            break;
        buffer = zrealloc(buffer, bufsize *= 2);
    }

t may be null.
