One minor thing you could do to optimize your code is use a switch statement.

Example with your code.

pawn Код:

switch(CurrentGamemode)
{
    // If Current Gamemode is equal to the value after "case" then it runs that code
    // So on and so forth.
    case 0:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        CurrentGamemode++; // adds one for the next time you call ChangeMode or w/e
    }
    case 1:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        CurrentGamemode++;
    }
    case 2:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        CurrentGamemode++;
    }
    case 3:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        CurrentGamemode++;
    }
    case 4:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        CurrentGamemode++;
    }
    case 5:
    {
        ServerMinutes = 0;
        ServerSeconds = 10;
        // if we've reached the final mode
        // we reset it to zero.
        CurrentGamemode = 0;
    }
}

Much more powerful than the if structure, and easier to read. I recommend you to look at that link. It tells you every thing about switch statements.
