I'd just like to add that Instant is not "more-or-less" opaque. It is
"entirely" opaque. That basically means it probably is architecture and
implementation dependant.

The point is... asking for "the amount of seconds since 01/01/1970"
requires you to convert that date, in a particular timezone in a
particular calendar (gregorian) to an instant, then ask for the amount
of seconds elapsed from that instant to the current instant (and that
will return you a Duration object (which conceptually only know about
TAI), which in turn can be converted (provided a timezone and a
calendar) to a Gregorian::Duration.
