So, you've never connected to server before, in other profile for example? Or maybe you're playing with savegame downloaded somewhere?

that is the reason ???

Or i need to reinstall game ?

Yes, once you get with your profile online, the game is starting to always check the weather on the server. So you need to create offline profile or find some savegame.

Try to delete the "//" part before "FORCE_OFFLINE_WEATHER", maybe it will help.

Do you know in which file is Time settings ? It must be changeable to

Unfortunately, no.

Another interesting bit:

In offline play, if you are unhappy that it always begins at the same time, consider this trick. It will relieve part of the annoyance by allowing you to experience a full day/night cycle in a much shorter period of real time. The effect is a little like time-lapse photography, especially if you use a very short period like a five-minute day. It greatly facilitates taking multiple screen captures in the right place and at the right time.

Edit your decrypted GamePC.cpr file and add a line for FORCED_OFFLINE_DAYLENGTH from the examples below. (I added them between the weather and the [Flash] section.)

...
...
...
//FORCED_OFFLINE_WEATHER = 0

//Parameter equals seconds of real time per one in-game day
FORCED_OFFLINE_DAYLENGTH = 300 //5-minute day - one 288th real time (try it!)
//FORCED_OFFLINE_DAYLENGTH = 600 //10-minute day - one 144th real time
//FORCED_OFFLINE_DAYLENGTH = 1800 //30-minute day - one 48th real time
//FORCED_OFFLINE_DAYLENGTH = 3600 //60-minute day - one 24th real time
//FORCED_OFFLINE_DAYLENGTH = 86400 //144-minute day - one-tenth real time (normal for offline)

i've tried it and worked day goes very fast and if this works why there is no possibility to set time ? or just freeze time

Forced_Offline_time does it work ?
