So I want to make an /ad command, but I want it so only 1 advertisement every 60seconds can be send.
I know how to code the command, but I don't really understand timers. Can somebody make a timer for me so it works?

My cmd:

Код:

CMD:ad(playerid, params[])
{
	if(isnull(params)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /ad [chat]");
	{
		new s[100];
		format(s,sizeof(s), "Advertisement: %s, Name: %s, Ph: %s", params, GetName(playerid), PlayerInfo[playerid][pPhone]);
		SendClientMessageToAll(COLOR_GREEN, s);
	}
	return 1;
}
