Hi there.

I've found that on admin serwer logs is wrong time.
Machine time is ok, also accounts time is ok even with setted diferent time zone.

Is there any way to change that time in centovacast config or something ?

EDIT

I've found option in cc-system.conf i have set EUROPE/LONDON, instead of default value.
Time have changed but still time in serwer log is wrong now its one hour back.
On my clock is 5:00 PM but it shows 4:00 PM

What logs are you referring to, exactly?  (Specific ones, or all of them?)

The option in cc-system.conf just tells PHP what time zone you want to use.  That will only change the times that PHP logs, it won't change anything else... everything else just uses your system time zone.
