I have ods file created with older LO versions, which use (Sheet - Link to outside data...) and pull data from CSV file. It worked without issues in 7.2.5, but when I upgraded to 7.3.0.2 date isn't recognized. This is sample data: 2022-01-22T06:50:59.400Z,buy,XYZ,36.991,16,591.856,USD,-0.373905028,1.1351 2022-01-22T10:57:25.501Z,buy,ZYX,33.968,8.8,298.9184,EUR,-0.0015884,1.13275 When linking CSV for first time, first column (date/time) was marked as "Date (YMD)", while columns 4, 5, 6, 8 and 9 were marked as US ENGLISH. This automatically converted first column to DATE format, and other columns to NUMBER format. As of 7.3.0.2 conversion to DATE isn't working any more (it just shows text string as it is), while conversion to NUMBER seams ok.
Thank you for reporting the bug. Please attach a sample document, as this makes it easier for us to verify the bug. I have set the bug's status to 'NEEDINFO'.

Created attachment 177735 [details] Test file Hello, sample data was provided in comment #1. I just saved in inside blank test.csv file. You can link file, then change csv file (copy last line, paste as new line, and change just starting date/time for example) and reload .ods file to see how it pulls new data.

While it's true that earlier versions accepted and ignored a timezone present in an ISO 8601 date+time, it's questionable that they did so, because there are no means to store the timezone information, it was simply discarded, which is a data loss. The commit message mentions that, "Also be more strict if ISO is detected and timezone is included keep it as type Text instead of silently discarding the timezone information."
