/** Format log messages own way in JSON.
* We can't obtain some details using Poco::PatternFormatter.
*
* Firstly, the thread number here is peaked not from Poco::Thread
* threads only, but from all threads with number assigned (see ThreadNumber.h)
*
* Secondly, the local date and time are correctly displayed.
* Poco::PatternFormatter does not work well with local time,
* when timestamps are close to DST timeshift moments.
* - see Poco sources and http://thread.gmane.org/gmane.comp.time.tz/8883
*
* Also it's made a bit more efficient (unimportant).
