Factually wrong. You can do a NAT rule to force it to whatever NTP you want. If you own the network, you can route the packets however you like.
Example from my opnsense config:
Nothing leaves my network on port 123 unless it's my own timeserver serving a response to an external request. (I actually have a proper GPS-based time server, but nothing stops you from just having a normal linux host as a timeserver or something this way either).
I do the same thing with DNS. Force all port 53 and 853 traffic to my own DNS servers. And have a wide firewall block rule for any known DoH servers.
Fair enough, I should have said that there's no other built-in way to set the time on them.
I work with 3d printers in a school that uses its own NTP server and blocks other requests. The only way I managed to set the time on the machines sort of using a raspberry pi or something, was to connect them to my phone's hotspot.
Ask the admins to setup the NAT rule.
But yeah, ultimately it's a pretty poor decision on Prusa's part to make it hardcoded. I didn't even realize my mk4 doesn't allow manually setting the time. I wonder if anyone has brought it up on the firmware repo.
I have DHCP announcing the NTP server, I haven't seen my prusa attempt to talk outside of my network. But I do see a boatload of IoT stuff ignore my local NTP all the time. Very frustrating.
I've opened an issue asking for a manual offline way to set the time, and I saw another one asking for a DHCP option.
I've tried asking the admins, and they were mad I connected the printers to the network to begin with 😅
