It is clearly a binary file, not text that could be read and understood without any documentation. I have just subscribed to this list and found this message. As it happens, I have been wondering how an assembly language program can determine the local time zone, so it can convert the seconds from 1-1-1970 to current local date and time (I am writing a FreeBSD assembly language tutorial, and want to cover this topic, so if the file structure is not described in any other doc, it will be in mine, that is, if someone points me in the direction which helps me decipher it).
