I am wondering why the timestamp of a system restore point (you get it by invoking [as admin] vssadmin LIST SHADOWS) differs 8-15 seconds with the timestamp shown in CCleaner?
The Tool Shadow Explorer (latest Version) shows no difference to vssadmin and has the same restore points.
Can you please check this regarding accuracy (I am forensic auditor and sometimes CCleaner is our tool of choice, but I do not want to explain differences of timestamps)
