Minor correction to the original poster: The location of a device does not determine its Stratum. Its location is irrelevant. A Stratum-0 device is any device that has a highly accurate internal clock which is synchronized with UTC time. (GPS Satellites are an example) A Stratum-1 device is any device that gets its time information directly from a Stratum-0 device. (A computer that gets its time information directly from a GPS signal) A Stratum-2 device is any device that gets its time information directly from a Stratum-1 device. (A computer that gets its time from a Stratum-1 computer over a network) ________________________________________ From: 44Net <44net-bounces+colereec=msu.edu(a)hamradio.ucsd.edu> on behalf of lleachii--- via 44Net <44net(a)hamradio.ucsd.edu> Sent: Sunday, January 31, 2016 9:17 PM To: 44net(a)hamradio.ucsd.edu Cc: lleachii(a)aol.com Subject: [44net] NTP - Reference (Please trim inclusions from previous messages) _______________________________________________ An inquiry was made into the Stratum of the NTP server: - Servers referenced are Stratum 1 or Stratum 2 Servers which reference a Stratum 0 Atomic Clock maintained by a University or Government Institution in Canada, the US or Mexico time-d.nist.gov nist1-pa.ustiming.org time.nist.gov time.nrc.ca time.chu.nrc.ca gnomon.cc.columbia.edu tick.gatech.edu cronos.cenam.mx _________________________________________ 44Net mailing list 44Net(a)hamradio.ucsd.edu http://hamradio.ucsd.edu/mailman/listinfo/44net
