I thought NTP specifically did account for transit latency. Not sure why I made that assumption, but if it’s not true, how can I ever trust my clock to be correct?


As the article says, it does account for it. It just can't account for unknown constant asymmetric latency.

what does it mean for your clock to be "correct"? If you need your time to be precise to more than a few 100ms you probably shouldn't be getting it from random NTP servers over unknown connections, but for most people that's an acceptable error.
