And that "millenium bug hoax" did have a root in fact
When I was a programmer, computer storage was SO expensive, we saved every byte we could every place we could
A date was dd/mm/yyyy (10 characters) - we could squeeze that do ddmmyyyy easily (now 8 characters) - by taking the "19" away (all dates had "19" as the start of the year - right?) we got to ddmmyy
If you store as yymmdd you could even sort on dates
991231 comes AFTER 980101
Snag is, after the Y2K, Jan 1st 2000 would become 000101 which comes BEFORE all of the 19xxxx dates
It really WAS a big deal and caused a lot of sweat and tears to put right
