DateTime is the most widely used implementation of ReadableInstant. As with all instants, it represents an exact point on the time-line, but limited to the precision of milliseconds. A DateTime calculates its fields with respect to a time zone. Internally, the class holds two pieces of data. Firstly, it holds the datetime as milliseconds from the Java epoch of TZ. Secondly, it holds a Chronology which determines how the millisecond instant value is converted into the date time fields. The default Chronology is ISOChronology which is the agreed international standard and compatible with the modern Gregorian calendar. All standard Chronology classes supplied are thread-safe and immutable. Since: 1. Property DateTime. Property binds a DateTime to a DateTimeField allowing powerful datetime functionality to be easily accessed.

This class is useful for representing human-based time of day, such as movie times, or the opening and closing times datetime java the local library. The calculation will do its best to only change the day field retaining the same time of day, datetime java.
