Hey - some people have a time question and I wonder if most people get the same list of time servers on BigSur? 
Non-authoritative answer:
time.apple.com	canonical name = time-osx.g.aaplimg.com.
Name:	time-osx.g.aaplimg.com
Address: 17.253.2.125
Name:	time-osx.g.aaplimg.com
Address: 17.253.2.253
Name:	time-osx.g.aaplimg.com
Address: 17.253.20.125
Name:	time-osx.g.aaplimg.com
Address: 17.253.24.125
Name:	time-osx.g.aaplimg.com
Address: 17.253.24.253
When they enter nslookup time.apple.com at a command prompt...
 
 
3 hours later…

Thanks @nohillside
I’ll have to get some results from my Macs in Asia and Oceania to fill the gaps. They are steering them to geographically close servers via dns. Pretty cool
