1638 Clock Class 52 and 187
Created: 19 Nov 2018
Status: Drafting Implementation
Category: Issue for edition 2 of this part
In 7.4.3, the definition of clock class 52 and 187 deviates from IEEE 1588 which specifies that a clock with class 52 may not be slave to another clock. Therefore, implementations adhering to 9-3 would differ from implementations adhering to 1588. Further, the indication of 1 us deviation is redundant since it is part of ClockAccuracy.
Use exactly the wording to IEEE 1588 Table 5 and insert as "holdover specification" the value given in C.7.4.1
