Re: [PATCH v4 06/21] test-date: add a subcommand to measure times in shell scripts

I think the goal to have our own stopwatch so that we do not have to
worry about differences among system-provided ones makes sense.

The only thing that may become an issue is how widely available
getnanotime() is.  As "test-date" itself is built on any platform an
end-user/developer runs our tests, which is wider set of platforms
than what we run Travis and other CIs on, unconditionally relying on
its availability might pose an issue.

Sorry for a false alarm, as the codebase in many places like
fsmonitor, progress, trace and wt-status have been assuming
getnanotime() to be available for quite some time, and this is just
another user of the same function.
