Subject: [RFC][PATCH 0/7] Start adding timetests to selftest

I've maintained a suite of timekeeping and timer tests for awhile
here: https://github.com/johnstultz-work/timetests

I've been meaning to get them reworked and submitted into the
selftest infrastructure, but haven't had much time recently.

I'm going to have a long flight coming up so I figured I'd
get started and get some initial feedback.

This series adds all the non-destructive tests from my
timetests suite. The suite has more tests which actually tweak
time state and validate things behave as expected, but I wasn't
sure how to integrate that into the selftest infrastructure
as I'm not sure everyone would want the tests to be mucking
with their system time. (Currently my plan is to add a
script similar to the runall.sh in timetests, so folks
can go in and manually run it if they're feeling daring)

Thoughts or comments here would be greatly appreciated!

thanks!
