Column 'date' with DateTime format

[Pl0414141]

Hello,

mostly parsers do not understand the following syntax of 'date' due do not have DateTime format in the CSV content:

date 20220128 00:00:00

I suggest convert to the following:

date 2022.01.28 00:00:00

I've never used that format before, but it seems reasonable to make the date format an option since users may have different preferences.
