Problem: I would like to use the value of a date custom field to create a custom post title with CRED.

Solution: The date field is not a simple text string in the $_POST object, but an array of values in this format:

[wpcf-date-field-slug] => Array
        (
            [display-only] => August 1, 2017
            [datepicker] => 1501545600
            [datetime] => 2017-08-01
            [hour] => 00
            [minute] => 00
            [timestamp] => 1501545600
        )

Use the cred_save_data hook to capture the custom date field information and update the post title as needed using one of these array values:

Or, you can format your own date using the timestamp value.
