Routing should be totally insignificant to the NTP offsets, since NTP measures the packet round-trip and recalculates the timestamps received. So, even if the packet needs thousands of milliseconds to get around the internet, your time should be +/- 1ms accurate. I'm runnig my pool servers in Germany, about 160ms away from Los Angeles, and the monitored offsets are not worse than 5ms. But, earlier this week I noticed, that one of the german Stratum 0 atomic clock servers located at PTB was also off by about 12-15 Seconds (yep, not milliseconds). Maybe a large wormhole appeared or it's just the time of year when big maintenance works on these servers are happening. Greetings, Max
