Uploading dates and times into a Matrix field:

The only way I’ve been able to import dates successfully is by using Unix timestamps in my import sheet and setting the FeedMe date format to “Auto.” However, even then, only about 60% of the dates are imported into the entries.

Here’s what I’ve tried so far:

• Updating FeedMe and Craft to the most recent versions
• Testing other formats (e.g., ISO and those listed in the format dropdown). The Unix timestamps from my sheet also fail to import when using the “timestamp (s)” format
• Adjusting the import sheet — formatting columns as strings and numbers, and exporting in both CSV and XML formats
• Checking the logs — interestingly, parsing errors only appear for the dates and times that were successfully imported. The rest seem to be completely omitted.
