Robbie came up with a date format which I modified a bit:
[+-]yyyy.mm.dd hh:mm:ss.nnn...<optional modifiers>
m/dd/yy or: April 1, 1984
stupid/oafish and beneath my dignity, ever since I first saw the European format , probably in college:
31 December 1999
Ditto the AM/PM time format. What's wrong with "military time", espacially for a bellicose country like The United States of America? But maybe most Americans or too lazy to count hours above 12, or too uneducated to be able to? Most Amerians are anti-intellectual, so what would one expect from them? To use the metric system (When are the Brits going to Brexit weights and measures, as well a their governance?)? 2 + 2 = Huh?
