Linux/Unix Time on CertCities

Although the posting date is given as 10/12, the article on time in Linux and Unix has recently posted on CertCities. A copy of the article can be found at http://www.certcities.com/editorial/columns/story.asp?EditorialsID=199. What is missing from the article, due to space constraints, is an in-depth discussion of how time is truly kept in terms of seconds past midnight, 1969. An article that included this was written for SysAdmin 10-12 years ago but badly needs updated. Hopefully, it will become a future article if time allows me to revisit the topic.
