Have an Advanced Insert Update to add the current date in a Salesforce field when the Document Package is run

Confirm that the tag is <<Today>>, not one of the modified versions in the Field tagger such as <<Today__s>>
If the client is using a date time field for the insert-update, <<Today>> will update the field as 5/5/2020 12:00AM regardless of what time the insert-update ran. if you want the time to be accurate, then you will need to use the  <<Now__h>> tag.
