Tell us what you are trying to do?
We wanted to import user data. One custom field that we want to populate has a date field type. When we tried to import, the date 2022/01/01 or other date format is not acceptable. So we exported the user data to see the value of that custom field in date. It turns out that the value is in timestamp. What can we do to make the date format acceptable? It would be hard for us to convert the date to timestamp first before importing.
Is there any documentation that you are following?
No, the thing is that when you create a custom date field using the Toolset Types plugin, the custom date field value is stored as Unix Timestamp to the database. That is why you will have to import the equivalent Unix Timestamp value for your date column.
