I already have that version of the specifications but I thought that we
were speaking about PC Client Platform spefication, which is at version
1.30. TCG spec is an ambiguous term so that is where the confusion
The only spec I've seen some timeouts is the PC Client Specification but
I guess I've then missed the list in TPM 2.0 spefication. Where are they
listed? I worked with Will Arthur durations based on PC Client Specification
when TPM 2.0 support was first implemented.
