I note the issue date is "04/09/02". Either this is a US "publication", and thankfully it died back in April, or it is UK publication, and they are a few days ahead of themselves. In either case, anyone that calls themselves a programmer and writes dates in such an ambiguous format is beneath contempt. Didn't they learn anything frm Y2K?
Seriously, when one is outputting dates, to avoid confusion between the US format and the "rest of the world" format, one should spell out the month name. Make it April 9, 2002 - at least those not from the US cannot misinterpret the date. Likewise, 4 September 2002 is equally clear to both US and non-Us readers.
And it should go without saying to include the century - 2002; not "02". Some people never learn.
