Well, from what you've posted, the only way that a player can level-up is by obtaining minutes which is obviously given every minute. So make a repeating timer for 1 minute.

Alright, let's start. First, declare a forward for the call-back.

pawn Код:

forward OneMinute();

Then set the timer

pawn Код:

public OnGameModeInit()
{
    SetTimer("OneMinute", 60000, 1);
    return 1;
}

For an explanation of the code above:
OneMinute would be the call-back as declared above, 60000 is the interval which is 1 minute, and the last parameter as 1 to identify it as repeating.

Next, let's create the actual call-back.

pawn Код:

public OneMinute()
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i))
        {
            // Create your own variables which I assume that you already have for each player.
            // That would be the enumeration(enum) on top of your script.
            PlayerStats[i][pMinutes]++; // this is just an example, change it with your actual variable.
        }
    }
    return 1;
}

On the call-back, it would loop through all the players online and would give them 1 point to their minutes variable.
