/**
 * Returns a copy of this {@code Instant} truncated to the specified unit.
 * <p>
 * Truncating the instant returns a copy of the original with fields
 * smaller than the specified unit set to zero.
 * The fields are calculated on the basis of using a UTC offset as seen
 * in {@code toString}.
 * For example, truncating with the {@link ChronoUnit#MINUTES MINUTES} unit will
 * round down to the nearest minute, setting the seconds and nanoseconds to zero.
 * <p>
 * The unit must have a {@linkplain TemporalUnit#getDuration() duration}
 * that divides into the length of a standard day without remainder.
 * This includes all supplied time units on {@link ChronoUnit} and
 * {@link ChronoUnit#DAYS DAYS}. Other units throw an exception.
 * <p>
 * This instance is immutable and unaffected by this method call.
 *
 * @param unit  the unit to truncate to, not null
 * @return an {@code Instant} based on this instant with the time truncated, not null
 * @throws DateTimeException if the unit is invalid for truncation
 * @throws UnsupportedTemporalTypeException if the unit is not supported
