Implementation of time.thread_time() doesn't work on Solaris because clock_id CLOCK_THREAD_CPUTIME_ID is not known (it is defined, but clock_gettime returns EINVAL error). Solaris, however, has function gethrvtime() which can substitute this functionality.

I attached a possible patch which does work during tests and I further tested it with some basic scripts.

Since I created this pull request, clock_gettime(CLOCK_THREAD_CPUTIME_ID, ..) was implemented into the Solaris kernel, so I guess that this is no longer relevant.

This issue is still valid under other solaris/sunos versions. @kulikjak are you still interested in resolving this issue?

I was speaking for Oracle Solaris 11.4, where CLOCK_THREAD_CPUTIME_ID is now implemented (and we don't need it in older releases). But you are right that other Solaris/SunOS versions might not have this and hence would find this useful.

I can rebase and reopen the original PR, but I cannot test it that well now that our Solaris doesn't use that part of the code (I can change the #define for testing, that should be sufficient).

Correction: looking at the PR, I made it so that it checks for SunOS, so even with CLOCK_THREAD_CPUTIME_ID available, new code would be executed. 

So if you believe that this should be implemented for other SunOSes, I can do it ;).

Comment from confirmed that this issue is still relevant to Illumos based systems. Because of that, I am happy to resolve it.

Perhaps we should also use gethrtime() and gethrvtime() on HP-UX, but this is a different issue.
