In TC 7.0.8 and later: The start time: = when org.apache.coyote.Request#setStartTime() is called That is done by processors. Some initial processing is already done at that point (e.g. reading the request line). The end time: = when org.apache.catalina.connector.CoyoteAdapter#service() calls logAccess(..) That is done when service() completes processing the request. At that point the content is already generated and response.finishResponse() is already called (which closes output buffer and writes remaining data to the socket). After that Tomcat performs cleaning of its internal state and is ready to process next request. I am not sure what you mean by "teardown". A correction: I wrote: > In latest versions of TC7 (7.0.8 and later) (...) > That version prints timestamp when request was received That is not true. With %t the AccessLogValve still prints the current time when logging is performed, not when processing was started. (There was a patch discussed on dev@ to change the behaviour, but it has not been applied yet).
