-- in a notification. End events sort before the corresponding start events as any ack/comment/downtime/flapping
-- period should last for more than a millisecond, therefore, the old period ends first and then the new one starts.
-- The remaining types are sorted by impact and cause: comments are informative, flapping is automatic and changes
