Gets a comparator that compares {@code ChronoZonedDateTime} _in
time-line order ignoring the chronology.
!(p)
This comparator differs from the comparison _in {@link #compareTo} _in that it
only compares the underlying instant and not the chronology.
This allows dates _in different calendar systems to be compared based
on the position of the date-time on the instant time-line.
The underlying comparison is equivalent to comparing the epoch-second and nano-of-second.
