How to set form submission date with API?

I have successfully submitted form through Escopecz\MauticFormSubmit\Mautic

https://github.com/escopecz/mautic-form-submit)

However the event_timestamp is generated by mautic system automatically. Can I manually set it because the real form submission date may be yesterday rather than now.

You need to hack it because submission date is generated by the system. You can’t overwrite it based on the docs.

Thank you for your reply。
