NYCMeshHistory: doesOver notthe years it has been evolving, changing. We used to use outside NTP, from the WWW , then one, and later a second member provided NTP. One via a Stratum-1 server (Antenna getting PPS via two u-blox receivers) the other one as a stratum-2 (chrony). Those 2 members moved on and another member started a new project at his "home lab" to provide NTP stratum-1. We have yetnow asetup Meshsome NTP server butusing 2chrony meshand memberswe arehave providingthe NTPmember's functionproject online (GPS PPS NTP/chrony server with a NEO 7M GPS unit on theira server.raspberry Pi.)
