-/**
- * @class AbsTime
- *
- * Class to represent an instant in time.
- *
- * The time resolution is in nanosecs, and this is held with 64 bits
- * giving a total time span from about 25 million years ago to 25 million
- * years hence. As an aside the internal time can sensibly be negative
- * meaning before the epoch (probably 1/1/1970 although this class doesn't
- * care).
- *
- * The AbsTime class is a value class and so you don't need to add any
- * accessors to its internal state. If you think you want to replace its value,
- * you need to construct a new AbsTime and assign it, viz:
- *
- * AbsTime when = now();
- * ...
- * when = AbsTime(when, 2*TIME_SEC); // Advance timer 2 secs
- *
- * AbsTime is not intended to be used to represent calendar dates/times
- * but you can construct a Duration since the Unix Epoch, 1970-1-1-00:00,
- * so that you can convert to a date/time if needed:
- *
- * int64_t nanosec_since_epoch = Duration(EPOCH, now());
- *
- * There are some sensible operations that are currently missing from
- * AbsTime, but nearly all that's needed can be done with a mixture of
- * AbsTimes and Durations.
- *
- * For example, convenience operators to add a Duration and AbsTime returning
- * an AbsTime would fit here (although you can already perform the operation
- * with one of the AbsTime constructors). However trying to add 2 AbsTimes
- * doesn't make sense.
