public final class Duration extends BaseDuration implements ReadableDuration, java.io.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.
Duration is thread-safe and immutable.

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 concept of 'days' you should consider using the Days
class.

This returns getMillis() / MILLIS_PER_DAY
.
The result is an integer division, thus excess milliseconds are truncated.

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() / MILLIS_PER_HOUR
.
The result is an integer division, thus excess milliseconds are truncated.
public long getStandardMinutes()
This method assumes that there are 60 seconds in a minute and 1000 milliseconds in a second. All currently supplied chronologies use this definition.
This returns getMillis() / 60000
.
The result is an integer division, thus excess milliseconds are truncated.
public long getStandardSeconds()
This method assumes that there are 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.
