 My intent, after finishing some mostly "cleanup" changes, is to review the
 open tickets (and PR) to see which might be straightforward enough to
 include in this release cycle.  One problem with anything clock-related is
 that it's hard to write an automated test for something that's a moving
 target, and the existing clock test is mainly just a manual test
 masquerading as an automated test, requiring manual scrutiny of the output
 for validity.  At least the rewritten version no longer treats out-and-out
 failures of the functions being tested as a "pass" (exposing one real bug
 in the process). :-)
