The reason for this thread was not to necessarily get the best possible 
time, but to get away from severely affected time that was causing the 
dataloss issues.

The one flaw that NTP has that motivated PTP was lack of hardware 
time-stamps. There are those that have implemented hardware 
time-stamping to NTP.

It's unfortunate to compare NTP and PTP when it should be comparing 
software time-stamping and hardware time-stamping.
