Yeah, It worked!
The only thing he gave me was a warning about sounds.
Code:
warning 234: symbol "IsSoundPrecached" is marked as deprecated: Doesn´t work correctly, always returns true.
So I tried it and it works. Something in itself, it was not what I thought I was going to do. Since you cannot modify or change the duration time, either in the console or in a cfg file. And that I have seen a gameplay on another server where you see how much time passes when the rescue vehicle arrives, and then the time stopped when a Tank was in play.
But hey, that must be a plugin author issue and I don't know if there is another plugin that allows something like that.
Thanks for the plugin fix.
