Problem with date hidden field

Hi, I have a problem with a hidden field that takes the current date in a form. I set the local date as the default, initially it works, but in the following days it doesn’t update the date. While in the metadata at the time of sending the date is correct. I think it’s a cache problem. can you help me solve this problem?

I also changed the date acquisition method using a shortcode that calls a php function. But the result doesn’t change.

Could disabling the PHP Resources Cache solve my problem?

Thank you!
