Could you be more specific which of many time-related syscalls do you
propose to include into the new class and why?

For example, choose your favorite architecture and list all syscalls
available on that architecture you'd like to see in that class, for one
reason or another.  This would help you to define the criteria of
selection for the proposed syscall class.
