[logback-dev] birthTime of the context

Hi Joern,

Could you reset the birthTime of the Context as I requested in LBCLASSIC-273? Please? :)

The birth time of the context designates the start time of the application (assuming logback was started at application launch). I don't think it makes sense to reset the birth time when the context is reset. For example, relative time would go backwards if birth time was reset which users may find confusing. -- Ceki http://twitter.com/#!/ceki
