is it possible to add delay on @broadcast?

[trizzy]

ACMD_FUNC(broadcast)
{
	nullpo_retr(-1, sd);

	memset(atcmd_output, '\0', sizeof(atcmd_output));

	if (!message || !*message) {
		clif_displaymessage(fd, msg_txt(sd,1149)); // Please enter a message (usage: @broadcast <message>).
		return -1;
	}

	sprintf(atcmd_output, "%s: %s", sd->status.name, message);
	intif_broadcast(atcmd_output, strlen(atcmd_output) + 1, BC_DEFAULT);

	return 0;
}

Anyone knows how? thanks.
