This works in reverse, it will add time
however display
05:00 04:59 ...

//start CountDownFromAmount = 0, stop 300

PHP Code:

public CountDownTimer(){  //This function must be performed every 1 second
    CountDownFromAmount++; 
    new string[128], timesmin, timessek; 
    timesmin = ((300-(CountDownFromAmount))/60);
    timessek = (300-((CountDownFromAmount)+((timesmin)*(60))));
    format(string, sizeof(string), "%02d:%02d", timesmin, timessek); 
    TextDrawSetString(Text:MissionCount, string); 
    TextDrawShowForAll(Text:MissionCount); 
    if(CountDownFromAmount == 300){ 
        GameTextForAll("", 3000, 5); 
    }
    return 1; 
}
