+ * Wrapper around RTTIMESPEC.

+ * @note Originally wanting to use RTTimeNanoTS rather than RTTimeNow.  The term
+ *       "absolute" was used for when the RTTimeNanoTS() value was converted to
+ *       something approximating unix epoch relative time with help of
+ *       RTTimeNow().  Code was later changed to just wrap RTTIMESPEC and drop
+ *       all usage of RTTimeNanoTS, ASSUMING that system time is stable.
