I have my preferences set to "%Y-%m-%d %H:%M:%S".
However, I have to check all of the dates. A receipt with "6 August 2009" comes through as "2009-06-08 00:00:00".
So the month and day are swapped - probably an inheritance of the US v. European date format differences, but this is no excuse! YYYY-MM-DD format is the ISO standard!
Worse still for a receipt with "16 August 2009" this comes through as "2009-08-16 00:00:00"!!!! Presumably because there can be no 16th month.
What a disaster. How can such inconsistencies pass through any decent quality controls, especially when accuracy is key to accounting.
