Gets the current millisecond _instant of the clock.
!(p)
This returns the millisecond-based _instant, measured from 1970-01-01T00:00Z (UTC).
This is equivalent to the definition of {@link System#currentTimeMillis()}.
!(p)
Most applications should avoid this method and use {@link Instant} to represent
an _instant on the time-line rather than a raw millisecond value.
This method is provided to allow the use of the clock _in high performance use cases
where the creation of an object would be unacceptable.
!(p)
The default implementation currently calls {@link #_instant}.
@return the current millisecond _instant from this clock, measured from
the Java epoch of 1970-01-01T00:00Z (UTC), not null
@throws DateTimeException if the _instant cannot be obtained, not thrown by most implementations
