Thanks Thorsten for the prompt reply. OK, we would love to use the existing Log4cxx buffering mechanism, but we found the time-stamp appended by Log4Cxx is the dequeue time rather than the enqueue time, so the question becomes is there any control over using the original log generating time instead of the delivery time?
