You can use the default log for this, using printf and gettime when player diconnects.

new LoginTime[MAX_PLAYERS];

public OnPlayerConnect(playerid)
{
    LoginTime[playerid] == gettime();
    return 1;
}

public OnPlayerDisconnect(playerid,reason)
{
    new n[24];
    GetPlayerName(playerid,n,24);
    printf("Player %s had been online for %s",ConvertSeconds(gettime() - LoginTime[playerid]));
}

stock ConvertSeconds(seconds) 
{ 
    new hours, mins, secs, string[50]; 
    hours = floatround(number / 3600); 
    mins = floatround((number / 60) - (hours * 60)); 
    secs = floatround(number - ((hours * 3600) + (mins * 60))); 
    new days = 0;
    if(hours >= 24) 
    { 
        days = floatround((hours/24), floatround_floor); 
        hours = hours % 24; 
    }
    if(days > 0) 
        format(string, 50, "%dd, %dh %dm and %ds", days, hours, mins, secs); 
    else if(hours > 0) 
        format(string, 50, "%dh %dm and %ds", hours, mins, secs); 
    else 
        format(string, 50, "%dm and %ds", mins, secs); 
    return string;
