How to create a report that uses the system date versus invoice date

SUGGESTED

Good afternoon, 

I am looking to create a report that I cant run daily that will detail all transactions recorded on the system date (audit log of activity). We recieve and prepare invoices using a variety of dates so I'm thinking the system date is a good constant to measure by. My intention is to use this report as a way to monitor accounts payable entries and accounts receivable invoices booked by newer users in my small department. Any ideas of alternative solutions would be greatly appreciated. 

Thank you in advance,
