Journal of events is a variant of the Monitoring Events sheet.
It is primarily specialized for the applicative events as it displays the original timestamps of their start and end dates (opposed to the recording timestamps which drive the Jeyzer monitoring events).
It is indeed more time accurate than the Monitoring Events sheet.
The Journal of Events displays the applicative event start and end dates with a green background. Jeyzer monitoring event dates will have instead a grey one (as above).
