WebThis process takes about 15 minutes on a normal server, after which it proceeds to the next step. Connect to all configured time servers, assess which ones are reliable (and therefor preferred), set local stratum to the lowest reliable server's stratum plus one. So if the lowest reliable server found is 1, then local will be 2.

WebJun 29, 2024 · The most accurate time source on a network (such as a hardware clock) occupies the lowest stratum level, or stratum one. This accurate time source is called a reference clock. An NTP server that acquires its time directly from a reference clock occupies a stratum that is one level higher than that of the reference clock. WebOct 27, 2024 · For example, clock C2's offset relative to C1 at a particular moment is Tc2 - Tc1, the instantaneous difference in time reported by C2 and C1. Resolution —The smallest unit by which a clock time is updated. Resolution is defined in terms of seconds. However, resolution is relative to the clock reported time and not to true time.
