Interface BasicDatetime

All Known Implementing Classes:

ZonelessDate, ZonelessDatetime, ZonelessTime, ZonelessTimestamp

public interface BasicDatetime

BasicDatetime is an interface for dates, times, or timestamps that can be assigned from a long value. The value to be assigned may either be a zoneless time, or it may be a zoned time.

A zoneless time is based on milliseconds. It may contain date and/or time components as follows:

 The time component = value % milliseconds in a day
 The date component = value / milliseconds in a day
 

If a date component is specified, it is relative to the epoch (1970-01-01).

A zoned time represents a time that was created in a particular time zone. It may contain date and/or time components that are valid when interpreted relative to a specified time zone, according to a Calendar. Jdbc types, such as Date typically contain zoned times.
