[GNC] Date format for QIF file

[ml at tgr66.me]

I’m developing QIF files to import my old investments. I get asked every time to confirm the date format (the entire import process is a bit long imo). The QIF specification says I ought to be able to enter a date using `dd month year`; for example: 29 December 2022. However, this results in an error in GnuCash.

Is there a format I can use in the files that GnuCash will accurately autodetect the correct format?

Thanks.
