Checks if the specified unit is supported.
!(p)
This checks if the specified unit can be added to or subtracted from this date.
If false, then calling the {@link #plus(long, TemporalUnit)} and
{@link #minus(long, TemporalUnit) minus} methods will throw an exception.
!(p)
The set of supported units is defined by the chronology and normally includes
all {@code ChronoUnit} date units except {@code FOREVER}.
!(p)
If the unit is not a {@code ChronoUnit}, then the result of this method
is obtained by invoking {@code TemporalUnit.isSupportedBy(Temporal)}
passing {@code this} as the argument.
Whether the unit is supported is determined by the unit.
@param unit the unit to check, null returns false
@return true if the unit can be added/subtracted, false if not
