So...

I gather a temporal mention to be appropriate beyond the definition of the Log. Also, most systems break off their logs by
size, not time. Although there is a definite time to each log, they are not consistent, even with the same log gatherer. Right or
wrong, that is how I find them. Suggestions below (if I may be so bold):

Circa 11:26, 23 Jul 2008, a note, claiming source Heinbockel, Bill <heinbockel (at) mitre (dot) org [email concealed]>, was sent to me:

From: "Heinbockel, Bill" <heinbockel (at) mitre (dot) org [email concealed]>

Event: The same state change may occur repeatedly.
Log Entry: No entry happens without context.
