So, is there any effect on 60 HZ equipment from this? Corrected or not?
Doubtful, since the only thing changing is the requirement to correct the accumulated time error. Experience tells me that typically, there will be 3-5 time error corrections a month. More often than not, they are to correct a slow time error ( - seconds). The requirements to maintain frequency still remain the same. They just aren't going to require the small accumulated errors that occur over time.
