Here, I'll show you an example:

Put this under OnGameModeInit:

pawn Код:

new bool:PlayerInGame[MAX_PLAYERS] = false;

Then when you want the player's 5 minute timer to start put this:

pawn Код:

SetTimerEx("GameOver", 300000, false, "d", playerid);
PlayerInGame[playerid] = true;

Then your OnPlayerEnter Checkpoint should look something like this:

pawn Код:

public OnPlayerEnterCheckpoint(playerid)
{
    if(PlayerInGame[playerid])
    {
        SendClientMessage(i, AAD_COLOR_RED, "Well done You have made it before the 5 minutes!!");
        /// Do Something here
    }
    else
    {
        SendClientMessage(i, AAD_COLOR_RED, "You're too late!");
    }
    return 1;
}

and put this somewhere in your script (outside any commands and callbacks), like right at the bottom of your script:

pawn Код:

public GameOver(playerid)
{
    SendClientMessage(playerid, 0xFF8080FF, "Game Over Bitch - You're 5 Minutes are up, too bad :P");
    PlayerInGame[playerid] = false;
    //// Do Something here to punish the player or whatever when his time is up.
    return 1;
}
