- org.joda.time.base.AbstractPartial
- - org.joda.time.base.BaseLocal
  - - org.joda.time.LocalDateTime

All Implemented Interfaces:

Serializable, Comparable<ReadablePartial>, ReadablePartial
```
public final class LocalDateTime
extends BaseLocal
implements ReadablePartial, Serializable
```
LocalDateTime is an unmodifiable datetime class representing a datetime without a time zone.
LocalDateTime implements the ReadablePartial interface. To do this, certain methods focus on key fields Year, MonthOfYear, DayOfYear and MillisOfDay. However, all fields may in fact be queried.
Internally, LocalDateTime uses a single millisecond-based value to represent the local datetime. This value is only used internally and is not exposed to applications.
Calculations on LocalDateTime are performed using a Chronology. This chronology will be set internally to be in the UTC time zone for all calculations.
Each individual field can be queried in two ways:
- getHourOfDay()
- hourOfDay().get()
The second technique also provides access to other useful methods on the field:
- numeric value
- text value
- short text value
- maximum/minimum values
- add/subtract
- set
- rounding
LocalDateTime is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

public LocalDateTime(Object instant,
                     Chronology chronology)
```
    Constructs an instance from an Object that represents a datetime, using the specified chronology.
    If the chronology is null, ISO in the default time zone is used. Once the constructor is completed, the zone is no longer used. If the instant contains a chronology, it will be ignored. For example, passing a LocalDate and a different chronology will return a date with the year/month/day from the date applied unaltered to the specified chronology.
    The recognised object types are defined in ConverterManager and include ReadablePartial, ReadableInstant, String, Calendar and Date. The String formats are described by ISODateTimeFormat.localDateOptionalTimeParser(). The default String converter ignores the zone and only parses the field values.

  - fromCalendarFields
```
public static LocalDateTime fromCalendarFields(Calendar calendar)
```
    Constructs a LocalDateTime from a java.util.Calendar using exactly the same field values.
    Each field is queried from the Calendar and assigned to the LocalDateTime. This is useful if you have been using the Calendar as a local date, ignoring the zone.
    One advantage of this method is that this method is unaffected if the version of the time zone data differs between the JDK and Joda-Time. That is because the local field values are transferred, calculated using the JDK time zone data and without using the Joda-Time time zone data.
    This factory method ignores the type of the calendar and always creates a LocalDateTime with ISO chronology. It is expected that you will only pass in instances of GregorianCalendar however this is not validated.
    
    Parameters:
    
    calendar - the Calendar to extract fields from, not null
    
    Returns:
    
    the created local date-time, not null
    
    Throws:
    
    IllegalArgumentException - if the calendar is null
    
    IllegalArgumentException - if the date is invalid for the ISO chronology
  - fromDateFields
```
public static LocalDateTime fromDateFields(Date date)
```
    Constructs a LocalDateTime from a java.util.Date using exactly the same field values.

    Parameters:
    
    date - the Date to extract fields from, not null
    
    Returns:
    
    the created local date-time, not null
    
    Throws:
    
    IllegalArgumentException - if the calendar is null
    
    IllegalArgumentException - if the date is invalid for the ISO chronology
  - size

public DateTime toDateTime(DateTimeZone zone)
```
    Converts this object to a DateTime using the specified zone.
    When the time zone is applied, the local date-time may be affected by daylight saving. In a daylight saving gap, when the local time does not exist, this method will throw an exception. In a daylight saving overlap, when the same local time occurs twice, this method returns the first occurrence of the local time.
    
    Parameters:
    
    zone - time zone to apply, or default if null
    
    Returns:
    
    a DateTime using the same millis

  - toLocalTime
```
public LocalTime toLocalTime()
```
    Converts this object to a LocalTime with the same time and chronology.
    
    Returns:
    
    a LocalTime with the same time and chronology
  - toDate
```
public Date toDate()
```
    Get the date time as a java.util.Date.
    The Date object created has exactly the same fields as this date-time, except when the time would be invalid due to a daylight savings gap. In that case, the time will be set to the earliest valid time after the gap.
    In the case of a daylight savings overlap, the earlier instant is selected.
    Converting to a JDK Date is full of complications as the JDK Date constructor doesn't behave as you might expect around DST transitions. This method works by taking a first guess and then adjusting. This also handles the situation where the JDK time zone data differs from the Joda-Time time zone data.
    
    Returns:
    
    a Date initialised with this date-time, never null
    
    Since:
    
    2.0
  - toDate
```
public Date toDate(TimeZone timeZone)
```
    Get the date time as a java.util.Date using the specified time zone.
    The Date object created has exactly the same fields as this date-time, except when the time would be invalid due to a daylight savings gap. In that case, the time will be set to the earliest valid time after the gap.
    In the case of a daylight savings overlap, the earlier instant is selected.
    Converting to a JDK Date is full of complications as the JDK Date constructor doesn't behave as you might expect around DST transitions. This method works by taking a first guess and then adjusting. This also handles the situation where the JDK time zone data differs from the Joda-Time time zone data.
    Unlike toDate(), this implementation does not rely on Java's synchronized time zone initialization logic, and should demonstrate better concurrent performance characteristics.
    
    Parameters:
    
    timeZone - the time zone
    
    Returns:
    
    a Date initialised with this date-time, never null
