Question about sgx_get_trusted_time

Sotiri_K_ — Fri, 05 May 2017 04:26:58 GMT

Hello,

I recently learned about the sgx_get_trusted_time function and it is useful in my work, but I have a couple questions about it that were not answered by the reference.

Does the use of the sgx_get_trusted_time function (or other platform services, for that matter) require use of the internet? If so, for what reason?
Under what circumstances will the time_source_nonce change?

I have a couple more questions but these are the most important for now. Any and all answers are greatly appreciated.

Thanks!

Thank you for your response.

Thank you for your response. Do you happen to know where I can find information about the second question as well?
