All Implemented Interfaces:: Comparable, ReadableDateTime, ReadableInstant, Serializable

public final class DateTime
extends BaseDateTime
implements ReadableDateTime, Serializable

DateTime is the standard implementation of an unmodifiable datetime class.

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 1970-01-01T00:00:00Z. 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.

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

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

Returns a copy of this datetime with the specified period added.

If the addition is zero, then this is returned.

This method is typically used to add multiple copies of complex period instances. Adding one field is best achieved using methods like withFieldAdded(DurationFieldType, int) or plusYears(int).

Parameters:: period - the period to add to this one, null means zero; scalar - the amount of times to add, such as -1 to subtract once
Returns:: a copy of this datetime with the period added
Throws:: ArithmeticException - if the new datetime exceeds the capacity of a long

plus

public DateTime plus(long duration)

Parameters:: duration - the duration, in millis, to add to this one
Returns:: a copy of this datetime with the duration added
Throws:: ArithmeticException - if the new datetime exceeds the capacity of a long

plus

public DateTime plus(ReadableDuration duration)

Returns a copy of this datetime with the specified duration added.

If the amount is zero or null, then this is returned. This datetime instance is immutable and unaffected by this method call.

Parameters:: duration - the duration to add to this one, null means zero
Returns:: a copy of this datetime with the duration added
Throws:: ArithmeticException - if the new datetime exceeds the capacity of a long

plus

public DateTime plus(ReadablePeriod period)

Returns a copy of this datetime with the specified period added.

This method will add each element of the period one by one, from largest to smallest, adjusting the datetime to be accurate between each.

Thus, adding a period of one month and one day to 2007-03-31 will work as follows: First add one month and adjust, resulting in 2007-04-30 Then add one day and adjust, resulting in 2007-05-01.

This method is typically used to add complex period instances. Adding one field is best achieved using methods like plusYears(int).

If the amount is zero or null, then this is returned. This datetime instance is immutable and unaffected by this method call.

Parameters:: period - the duration to add to this one, null means zero
Returns:: a copy of this datetime with the period added
Throws:: ArithmeticException - if the new datetime exceeds the capacity of a long

plusYears

public DateTime plusYears(int years)

Returns a copy of this datetime plus the specified number of years.

The calculation will do its best to only change the year field retaining the same month of year. However, in certain circumstances, it may be necessary to alter smaller fields. For example, 2008-02-29 plus one year cannot result in 2009-02-29, so the day of month is adjusted to 2009-02-28.

The following three lines are identical in effect:

 DateTime added = dt.plusYears(6);
 DateTime added = dt.plus(Period.years(6));
 DateTime added = dt.withFieldAdded(DurationFieldType.years(), 6);

This datetime instance is immutable and unaffected by this method call.

Parameters:: years - the amount of years to add, may be negative
Returns:: the new datetime plus the increased years
Since:: 1.1

plusMonths

public DateTime plusMonths(int months)

Returns a copy of this datetime plus the specified number of months.

The calculation will do its best to only change the month field retaining the same day of month. However, in certain circumstances, it may be necessary to alter smaller fields. For example, 2007-03-31 plus one month cannot result in 2007-04-31, so the day of month is adjusted to 2007-04-30.

The following three lines are identical in effect:

 DateTime added = dt.plusMonths(6);
 DateTime added = dt.plus(Period.months(6));
 DateTime added = dt.withFieldAdded(DurationFieldType.months(), 6);

This datetime instance is immutable and unaffected by this method call.

Parameters:: months - the amount of months to add, may be negative
Returns:: the new datetime plus the increased months
Since:: 1.1

plusWeeks

public DateTime plusWeeks(int weeks)

Returns a copy of this datetime plus the specified number of weeks.

The calculation operates as if it were adding the equivalent in days.

 DateTime added = dt.plusWeeks(6);
 DateTime added = dt.plus(Period.weeks(6));
 DateTime added = dt.withFieldAdded(DurationFieldType.weeks(), 6);

This datetime instance is immutable and unaffected by this method call.

Parameters:: weeks - the amount of weeks to add, may be negative
Returns:: the new datetime plus the increased weeks
Since:: 1.1

plusDays

public DateTime plusDays(int days)

Returns a copy of this datetime plus the specified number of days.

The calculation will do its best to only change the day field retaining the same time of day. However, in certain circumstances, typically daylight savings cutover, it may be necessary to alter the time fields.

In spring an hour is typically removed. If adding one day results in the time being within the cutover then the time is adjusted to be within summer time. For example, if the cutover is from 01:59 to 03:00 and the result of this method would have been 02:30, then the result will be adjusted to 03:30.

The following three lines are identical in effect:

 DateTime added = dt.plusDays(6);
 DateTime added = dt.plus(Period.days(6));
 DateTime added = dt.withFieldAdded(DurationFieldType.days(), 6);

This datetime instance is immutable and unaffected by this method call.

Parameters:: days - the amount of days to add, may be negative

Since:: 1.1

plusHours

public DateTime plusHours(int hours)

Returns a copy of this datetime plus the specified number of hours.

The calculation will add a duration equivalent to the number of hours expressed in milliseconds.

For example, if a spring daylight savings cutover is from 01:59 to 03:00 then adding one hour to 01:30 will result in 03:30. This is a duration of one hour later, even though the hour field value changed from 1 to 3.

The following three lines are identical in effect:

 DateTime added = dt.plusHours(6);
 DateTime added = dt.plus(Period.hours(6));
 DateTime added = dt.withFieldAdded(DurationFieldType.hours(), 6);

This datetime instance is immutable and unaffected by this method call.

minus

public DateTime minus(ReadablePeriod period)

Returns a copy of this datetime with the specified period taken away.

This method will subtract each element of the period one by one, from largest to smallest, adjusting the datetime to be accurate between each.

Thus, subtracting a period of one month and one day from 2007-05-31 will work as follows: First subtract one month and adjust, resulting in 2007-04-30 Then subtract one day and adjust, resulting in 2007-04-29. Note that the day has been adjusted by two.

This method is typically used to subtract complex period instances. Subtracting one field is best achieved using methods like minusYears(int).

If the amount is zero or null, then this is returned. This datetime instance is immutable and unaffected by this method call.

Parameters:: period - the period to reduce this instant by
Returns:: a copy of this datetime with the period taken away
Throws:: ArithmeticException - if the new datetime exceeds the capacity of a long
