I want to use ZK calendar with java 8 date types (java.time.LocalDate, java.time.LocalDateTime, java.time.LocalTime) instead of old java.util.Date.
Please provide a SimpleCalendarEvent that can deal with java.time API and a built-in formatter for those types, as the current org.zkoss.calendar.api.DateFormatter.
1. As an app developer, I want to use a java 8 new Date/Time class (java.time.*) to create a Calendar item, so that I can implement the application logic without converting to java.util.date
2. As an app developer, I want to implement my custom date formatter with java 8 new Date class without converting from java.util.date
