time zone article

[Joe Celko [71062,1056]]

I am writing a book on data and databases.  I need a short piece on 
timezones, UTC, leap seconds, etc. for the section on temporal data.  If 
anyone has the time (pun) and would like to contribute, I can pay them a few 
bucks for their effort.  I am more interested in getting the data than in 
getting a finished ready-to-publish article.

Here is my biosketch by way of introduction:
