In your previous post, you gave the pattern used for logging:

Kea logging is built on log4cplus, and the pattern specification is the
one used by that package.  The log4cplus manual at:


says that "%d{...}" outputs the time in UTC.

The web site associated with your email domain (nicram.net) is in
Polish. Poland is currently on CEST, two hours ahead of UTC.  This would
account for the discrepancy you are seeing.

Try changing your pattern from "%d{...}" to "%D{...}", which will output
the time in local time.
