To prevent the undetected adulteration of files that have the potential to threaten the security and integrity of your system, this download was digitally signed.
Although digital signatures cannot prevent the unintentional or intentional corruption of signed files, they are an effective safeguard against the corruption remaining undetected, in that the authenticity and integrity of a file can be easily determined by operating system or third party software, or if need be, manually. The information on this page has been provided for the latter of these cases.

*1 UTC is the abbreviation for Universal Time Coordinated (aka Greenwich Mean Time (GMT)). Your application may show this date and time converted into your local date and time or Central European daylight saving time. In this case, you have to add/subtract the number of hours you're ahead or behind of Greenwich time (or 2 hours) to compare it to the dates and times specified on this page.
*2 This is the date and time (without the " Z ...") that would typically be displayed on the first page of the (downloaded) file's properties dialog, if you set your system's time zone to Greenwich Mean Time (GMT). In other words: This is the file system timestamp for the time of the last modification.
*3 This is the date and time (in ISO format, which is: yyyy/mm/dd hh:mm:ss) as displayed on the signature properties dialog under Adobe Acrobat Readers from version 8, up to and including, (at least) 11. Unfortunately, this is erroneous in that
1. The date and time specified on this dialog are that of the current, local time (in our case, Central European, daylight saving time, i.e. GMT +02 hours, 00 minutes) and not the UTC (aka GMT), as insinuated by " +02'00' ".
2. " +02'00' " (the ' denoting minutes) stands for "+02 minutes and 00 minutes" and not for +2 hours and 0 minutes, as would be more appropriate, but still incorrect, as this would equate to a local (Central European), daylight saving time of 23:09:15, which would be (nearly) 4 hours after the file system registered the last modification (i.e. wrong).
This is simply sloppiness on the part of Adobe.
If specified correctly in ISO format the date and time of signing should read
2022/02/08 19:09:15 +02:00 (UTC), or in a more user friendly notation
Tuesday, February 08, 2022, 19:09:15 Z (UTC), the "(UTC)" merely emphasizing that Universal Time Coordinated was specified.
*4 Although we are fully aware of the theoretical advantages (and the underlying concepts) of an independent certificate auhtority, we are currently reviewing the effective/practical aspects (reliable non-repudiation being one) of such certificates for .pdf documents. In the meantime, we can only provide a signature based on a self-signed certificate and you will have to decide for yourself whether or not to trust this document.
"CN = Dominic Stoelzel OU = Management O = SARL Stoelzel Software Technologie (SST) C = FR" is the Light Weight Directory Access Protocol (LDAP) notation that identifies the signatory, wherein CN stands for Common Name, OU for Organizational Unit, O for Organization, and C for Country.
*5 A thumbprint is identical to/synonymous with a hash and a digest.
