From what I understood, you want a command that is toggled by the player every few minutes. If that's the case, I'd recommend that you use a timeout instead of using timers if you're gonna use something that is especifically toggled by the player, although you would have to calculate the time left if you're gonna make it something like "you can't use this command until x minutes have passed".

//Check the tickcount function in SA-MP Wiki.

}

getPlayerTimeout(playerid, timeoutname[], time) {
    return (tickcount() - GetPVarInt(playerid, coolname)) > (time * 1000);
        //The time argument is used in seconds, then it's converted to ms.
        //This will also return true if the timeout hasn't been set.
}

destroyPlayerTimeout(playerid, timeoutname[]) {
