public final class Duration extends BaseDuration implements ReadableDuration, Serializable
A duration is defined by a fixed number of milliseconds.
There is no concept of fields, such as days or seconds, as these fields can vary in length.
A duration may be converted to a Period
to obtain field values.
This conversion will typically cause a loss of precision however.
Duration is threadsafe and immutable.
Modifier and Type  Field and Description 

static Duration 
ZERO
Constant representing zero millisecond duration

Constructor and Description 

Duration(long duration)
Creates a duration from the given millisecond duration.

Duration(long startInstant,

Creates a duration from the given interval endpoints.

Duration(Object duration)
Creates a duration from the specified object using the
ConverterManager . 
Duration(ReadableInstant start,
ReadableInstant end)
Creates a duration from the given interval endpoints.

 if duration is invalidpublic static Duration standardDays(long days)
This method assumes that there are 24 hours in a day, 60 minutes in an hour, 60 seconds in a minute and 1000 milliseconds in a second. This will be true for most days, however days with Daylight Savings changes will not have 24 hours, so use this method with care.
A Duration is a representation of an amount of time. If you want to express
the concepts of 'days' you should consider using the Days
class.

This method assumes that there are 60 minutes in an hour, 60 seconds in a minute and 1000 milliseconds in a second. All currently supplied chronologies use this definition.

This returns getMillis() / 1000

The result is an integer division, so 2999 millis returns 2 seconds.
