Regrettably, the only reasonably detailed list of stratum one and two 
_NTP_ servers that I'm aware of is that on ntp.org - 
https://support.ntp.org/bin/view/Servers/WebHome - and it obviously 
doesn't offer any fields for advising of NTS support.

As a workaround, I just updated my own listing and added "NTS Enabled" 
to the 'HostOrganization' field, which does provide a serviceable 
informational entry in the overall listing. Obviously wouldn't work for 
orgs that use that field, but it's a start.
