Time accelerating problem

Hi to all. I tried that sript and that not worked for me.

Code:

---

    private ["_lastrain", "_rain", "_fog", "_mintime", "_maxtime", "_overcast", "_realtime", "_random","_startingdate", "_startingweather", "_timeforecast", "_daytimeratio", "_nighttimeratio", "_timesync", "_wind"];
   
    // Real time vs fast time
    // true: Real time is more realistic weather conditions change slowly (ideal for persistent game)
    // false: fast time give more different weather conditions (ideal for non persistent game)
    _realtime = false;

    // Random time before new forecast
    // true: forecast happens bewteen mintime and maxtime
    // false: forecast happens at mintime
    _random = false;

    // Min time seconds (real time) before a new weather forecast
    _mintime = 600;

    // Max time seconds (real time) before a new weather forecast
    _maxtime = 1200;

    // If Fastime is on
    // Ratio 1 real time second for x game time seconds
    // Default: 1 real second = 6 second in game
    _daytimeratio = 6;
    _nighttimeratio = 24;

    // send sync data across the network each xxx seconds
    // 60 real seconds by default is a good value
    // shortest time do not improve weather sync
    _timesync = 60;

    // Mission starting date is 25/09/2013 at 12:00
    _startingdate = [2015, 07, 01, 07, 00];

    // Mission starting weather "CLEAR|CLOUDY|RAIN";
    _startingweather = ["CLEAR", "CLOUDY", "RAIN"] call BIS_fnc_selectRandom;

    /////////////////////////////////////////////////////////////////
    // Do not edit below
    /////////////////////////////////////////////////////////////////
   
    if(_mintime > _maxtime) exitwith {hint format["Real weather: Max time: %1 can no be higher than Min time: %2", _maxtime, _mintime];};
    _timeforecast = _mintime;

    setdate _startingdate;
    switch(toUpper(_startingweather)) do {
        case "CLEAR": {
            wcweather = [0, 0, 0, [random 3, random 3, true], date];

    // add handler
    if (local player) then {
        wcweatherstart = true;
        "wcweather" addPublicVariableEventHandler {
            // first JIP synchronization
            if(wcweatherstart) then {
                wcweatherstart = false;
                skipTime -24;

Who know's how to accelerate in game time?
