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.
Duration is threadsafe 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 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.
This returns getMillis() / MILLIS_PER_DAY
.
The result is an integer division, thus excess milliseconds are truncated.
public long getStandardHours()
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() / MILLIS_PER_MINUTE
.
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.
