This category is for sites with information and comments about International Standard ISO 8601, the Date and Time Standard now officially adopted in nearly every country of the world. This standard defines various formats based on Year-Month-Day for Dates, and Hours:Minutes:Seconds for Time, as well as covering the numbering of Days within the Year, Months and Weeks within the Year, and Days within the Week.
This standard was a core requirement for Year 2000 Fixes, and is highly recommended for all new computer protocols, databases, and much other work. There are hundreds of sites with useful information. This category will feature many of the best of these. There is also a mailing list where users can find advice from other users. This is on YahooGroups, and listed within this category.
