Windows 10: Black Lotus Revocation Issue: Should I Be Worried About The Digital Signature Timestamp...

Hello All I was trying to harden up my Windows 10 Enterprise install and I had what I thought might be a little issue. I was following the instructions for the Black Lotus set of revocations for the my boot manager detailed here When I got to the end of step 2 part D.: step IV I checked the digital signatures on bootmgfw_2023.efi and everything was matching what was to be expected from the article except for the date listed in the digital signature page was a little more than 7 days off. This made me worry and I was just wondering if I should be worried and if so, how I should fix the prob
