/**
* A date-time without a time-zone in an arbitrary chronology, intended
* for advanced globalization use cases.
* <p>
* <b>Most applications should declare method signatures, fields and variables
* as {@link LocalDateTime}, not this interface.</b>
* <p>
* A {@code ChronoLocalDateTime} is the abstract representation of a local date-time
* where the {@code Chrono chronology}, or calendar system, is pluggable.
* The date-time is defined in terms of fields expressed by {@link TemporalField},
* where most common implementations are defined in {@link ChronoField}.
* The chronology defines how the calendar system operates and the meaning of
* the standard fields.
*
* <h3>When to use this interface</h3>
* The design of the API encourages the use of {@code LocalDateTime} rather than this
* interface, even in the case where the application needs to deal with multiple
* calendar systems. The rationale for this is explored in detail in {@link ChronoLocalDate}.
* <p>
* Ensure that the discussion in {@code ChronoLocalDate} has been read and understood
* before using this interface.
*
* <h3>Specification for implementors</h3>
* This interface must be implemented with care to ensure other classes operate correctly.
* All implementations that can be instantiated must be final, immutable and thread-safe.
* Subclasses should be Serializable wherever possible.
*
* @param <C> the chronology of this date-time
* @since 1.8
