While a bit off-topic in this thread, still a quick/brief response, as it _seems_ there _might_ be some misconceptions here.

Ok, understand the formal/legal point, even if mostly irrelevant from technical point of view, or even counterproductive.

Depending on circumstances, this _may_ actually be rendered _more_ difficult by everyone syncing to PTB’s timeservers.

Again, this _may_ be _less_ accurate when syncing to PTB timeservers than otherwise technically possible.

As above.

NTP and UTC have _nothing_ to do with daylight saving time whatsoever, or with local time, e.g., “german time”, regardless of whether provided by PTB or any other source. It is a matter entirely [local to each individual system](https://community.ntppool.org/t/daylight-saving-time/2830) to “translate” UTC/NTP time to the local time/time zone for presentation, including considerations regarding DST.
