Test different date pattern

[geofranzi]

could be done manually, but maybe its only a little bit of copy past to have it automated ;).

We recently found the date pattern yyyy creates invalid data after upload. Can you make a CSV file where we have each data pattern once inside (one per column) and create a data structure that fits it? After uploading, check the result table to see if everything fits.

my data -> select table -> check here if "input" = "output"
