Since you're using settimerex, you probably need truckmission-timer for all players: truckmission[MAX_PLAYERS]
and you dont need to loop through all players in this timer:

pawn Код:

public TruckTimer(playerid)
{
  TimeS[playerid]--;
  if(TimeS[playerid] < 0)
  {
    TimeS[playerid] = 59;
    TimeM[playerid]--;
    if(TimeM[playerid] < 0)
    {
      SendClientMessage(playerid, COLOR_ORANGE, "[INFO] Time ended, mission aborted.");
      KillTimer(truckmission[playerid]);
      //the rest code
    }
  }
  new str[10];
  format(str, sizeof(str), "%d:%02d", TimeM[playerid], TimeS[playerid]);
  TextDrawSetString(Timer[playerid][1], str);
  TextDrawShowForPlayer(playerid, Timer[playerid][1]);
}
