Due to use of TimedRotatingFileHandler, my log behaves differently after midnight. I got to know why it is so but couldn't get how I can solve it.

The usual logging usage pattern is:
the individual components decide what to log
but how the logging happens it decided centrally - common
for all components.
This implies that usually the individual components do not handle
handlers or formatters but use the configuration set up centrally.
