Hi, I have the private server run in CentOS server, my server time is correct (GMT +7) but game time not correct. Please guide me how to fix it?

Hi there,

as far as I am aware, you currently cannot change gametime (ingame game time, which displays on the map of each player). I have written such a method myself, but it still isn't perfect. It lets me adjust the time though.

The class you should have a look at, is "GameTimeController". I simply added a setter method for the time. It seems to adjust the time (along with sending the proper packet to all available players), but the conversion from server time to ingame-time is a bit difficult.

Added setGameTime in GameTimeController.java:

Code: Select all

     public final void setGameTime(int hour, int minute, int second)    {        final Calendar c = Calendar.getInstance();        c.set(Calendar.HOUR_OF_DAY, hour);        c.set(Calendar.MINUTE, minute);        c.set(Calendar.SECOND, second);        c.set(Calendar.MILLISECOND, 0);        _referenceTime = c.getTimeInMillis();    } 

Created "GameTime"-L2Script, which adds the admin commands "settime" (admin_settime) and "srt" (admin_srt).
The code still contains errors, but you get the idea. I didn't have time to fix them yet.

Code: Select all
