/**
* Simple converter from Java 8's {@link java.time.ZonedDateTime} to {@link java.util.Calendar}.
*
* <p>Note that Spring's default ConversionService setup understands the 'from'/'to' convention
* that the JSR-310 {@code java.time} package consistently uses. That convention is implemented
* reflectively in {@link ObjectToObjectConverter}, not in specific JSR-310 converters.
* It covers {@link java.util.GregorianCalendar#toZonedDateTime()} as well, and also
* {@link java.util.Date#from(java.time.Instant)} and {@link java.util.Date#toInstant()}.
