[rules-users] replace session clock at runtime

Drools 5.5 Hey guys, Is it possible to replace the session clock of an existing stateful knowledge session (STREAM mode) while it is running or at least by pausing and restarting it? I need to feed old events into the session to restore a certain session state before switching the sessions to "realtime" mode and continue with new incoming events... A code snippet would make me very happy ;) - Alex
