about accurate of gptp clock values #12

Closed ibpswyz closed 2 years ago

ibpswyz commented 2 years ago

Hello, this project is great and it has run on my machines successfully. I get gptp clock values by using function 'gptpmasterclock_getts64()'. But there is a question: the execution time of the function 'gptpmasterclock_getts64()' is about 3 to 4 microseconds. Does this mean that the gptp clock value obtained is only microseconds accurate? I am looking forward to your answer. Thanks a lot!
