I'm having a bit of a hard time with a few events in our game's log files. I would've changed the logging format, but it is part of the game engine which means I cannot just change it.

Ideally all these lines without a timestamp should receive the timestamp from the first line. What's the proper way of doing this?
It would also be okay if all events without timestamp were to be indexed as a multiline events, but right now the game's build date in line 5 is being interpreted as event timestamp and prevents splunk from grouping the events without timestamp together.
