I am having a debate with our CIO. He wrote in a memo about timing: *Local hardware is to be considered Stratum 1, since it get time from its own CMOS.* I told him that absurd and that it can't be considered stratum 1. -------------------------------------------- Hmmmmmmmm So any dodgy PC clock is now Stratum 1 by his definition? The following is just one quick example from a google search and came from....... http://www.endruntechnologies.com/stratum1.htm ---------------------------- What is Stratum 1? In the world of NTP, stratum levels define the distance from the reference clock. A reference clock is a stratum-0 device that is assumed to be accurate and has lttle or no delay associated with it. The reference clock synchronizes to the correct time (UTC) using long wave radio signals, GPS transmissions, CDMA technology or other time signals such as WWV, DCF77, etc. Stratum-0 servers cannot be used on the network, instead, they are directly connected to computers which then operate as stratum-1 servers. A server that is directly linked to a stratum-0 device is called a stratum-1 server. This includes all time servers with built-in stratum-0 devices and those with direct links to stratum-0 devices such as over an RS-232 connection or via an IRIG-B time code. The basic definition of a stratum-1 time server is that it be directly linked (not over a network path) to a reliable source of UTC time such as GPS, WWV, or CDMA transmissions. A stratum-1 time server acts as a primary network time standard. --------------------------------- See what he makes of that :-) regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
