A date-time without a time zone in the ISO-8601 calendar system, such as '2007-12-03T10:15:30'.
LocalDateTime is an immutable calendrical that represents a date-time, often viewed as year-month-day-hour-minute-second. This object can also access other fields such as day of year, day of week and week of year.
This class stores all date and time fields, to a precision of nanoseconds. It does not store or represent a time zone. Thus, for example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in an LocalDateTime.
LocalDateTime is immutable and thread-safe.
