newbienoob - There's a method that is much better than that , I will share it to you, you could use the function gettime, to create a timer for a command, I used to use the first method, creating a second timer and loop it, but when the callback gets larger, You will experience lag, but the code below is just amazing

pawn Code:

CMD:healme(playerid, params[])
{
    static 
        HealTimer[ MAX_PLAYERS ] = { 0, ... }
    ;

    if( (gettime( ) - HealTimer[playerid] ) < 60) 
        return SendClientMessage(playerid, -1, "Please wait 1 minute before using this command again!");

    HealTimer[playerid] = gettime();

    SetPlayerHealth(playerid, 100);
    IsHealed[playerid] = 1;
    return 1;
}
