See https://bugs.ruby-lang.org/issues/8658

2.1 will add an unofficial API to get OS-level clock values like CLOCK_MONOTONIC and gettimeofday. I have commented on the bug about what these are on JVM and how we should probably proceed.

Note that in the developer meeting transcript linked from the above issue, matz says this is not considered "spec" and other implementations do not need to implement it...but I'm sure we'll have to anyway since there's no alternative.

Partial impl committed. If we use native calls we could cover more clock types, but REALTIME and MONOTONIC probably cover 90% of uses. Leaving open to decide if we want to go deeper.

We'll go deeper when someone requests deeper. This is working for 99% cases now.
