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:

The second technique also provides access to other useful methods on the field:

LocalDateTime is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

Method Detail

now

public static LocalDateTime now()
Obtains a LocalDateTime set to the current system millisecond time using ISOChronology in the default time zone. The resulting object does not use the zone.

Returns:
the current date, not null
Since:
2.0

now

public static LocalDateTime now(DateTimeZone zone)
Obtains a LocalDateTime set to the current system millisecond time using ISOChronology in the specified time zone. The resulting object does not use the zone.

Parameters:
zone - the time zone, not null
Returns:
the current date, not null
Since:
2.0

now

public static LocalDateTime now(Chronology chronology)
Obtains a LocalDateTime set to the current system millisecond time using the specified chronology. The resulting object does not use the zone.

Parameters:
chronology - the chronology, not null
Returns:
the current date, not null
Since:
2.0

parse

public static LocalDateTime parse(String str)
Parses a LocalDateTime from the specified string.

This uses ISODateTimeFormat.localDateOptionalTimeParser().

Parameters:
str - the string to parse, not null
Since:
2.0

parse

public static LocalDateTime parse(String str,
                                  DateTimeFormatter formatter)
Parses a LocalDateTime from the specified string using a formatter.

Parameters:
str - the string to parse, not null
formatter - the formatter to use, not null
Since:
2.0

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
Returns:
the created LocalDateTime
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.

Each field is queried from the Date and assigned to the LocalDateTime. This is useful if you have been using the Date 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 always creates a LocalDateTime with ISO chronology.

Parameters:
date - the Date to extract fields from
Returns:
the created LocalDateTime
Throws:
IllegalArgumentException - if the calendar is null
IllegalArgumentException - if the date is invalid for the ISO chronology

a DateTime using the same millis

toLocalDate

public LocalDate toLocalDate()
Converts this object to a LocalDate with the same date and chronology.

Returns:
a LocalDate with the same date and chronology

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

withDate

public LocalDateTime withDate(int year,
                              int monthOfYear,

Returns a copy of this datetime with the specified date, retaining the time fields.

If the date is already the date passed in, then this is returned.

To set a single field use the properties, for example:

 DateTime set = dt.monthOfYear().setCopy(6);
 

Parameters:
year - the new year value
monthOfYear - the new monthOfYear value
dayOfMonth - the new dayOfMonth value
Returns:
a copy of this datetime with a different date
Throws:
IllegalArgumentException - if any value if invalid

                              int millisOfSecond)
Returns a copy of this datetime with the specified time, retaining the date fields.

If the time is already the time passed in, then this is returned.

To set a single field use the properties, for example:

Parameters:
hourOfDay - the hour of the day
minuteOfHour - the minute of the hour
secondOfMinute - the second of the minute

withFields

public LocalDateTime withFields(ReadablePartial partial)
Returns a copy of this datetime with the partial set of fields replacing those from this instance.

Returns:
a copy of this datetime with a different set of fields
Throws:
IllegalArgumentException - if any value is invalid

For example, if the field type is hourOfDay then the hour of day field would be changed in the returned instance. If the field type is null, then this is returned.

These three lines are equivalent:

 LocalDateTime updated = dt.withField(DateTimeFieldType.dayOfMonth(), 6);
 LocalDateTime updated = dt.dayOfMonth().setCopy(6);
 LocalDateTime updated = dt.property(DateTimeFieldType.dayOfMonth()).setCopy(6);
 

Parameters:
fieldType - the field type to set, not null

 LocalDateTime added = dt.plus(Period.years(6));
 

Parameters:
