/** Format log messages own way.
|
|
* 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).
