The full timeline is valuable since you can look back on it and determine what went wrong when, so you can determine what changes need to happen to prevent these same issues in the future.
One thing I find is that incident reports such as these are most useful internally, but when communicated externally, they demonstrate that you're taking the underlying issues seriously and are committed to addressing them.
