# Duration

`@ExperimentalTime inline class Duration : `

Comparable<Duration>

Represents the amount of time one instant of time is away from another instant.

A negative duration is possible in a situation when the second instant is earlier than the first one. An infinite duration value Duration.INFINITE can be used to represent infinite timeouts.

To construct a duration use either the extension function toDuration, or the extension properties hours, minutes, seconds, and so on, available on Int, Long, and Double numeric types.

To get the value of this duration expressed in a particular duration units use the functions toInt, toLong, and toDouble or the properties inHours, inMinutes, inSeconds, inNanoseconds, and so on.

### Properties

#### absoluteValue

Returns the absolute value of this value. The returned value is always non-negative.

`val absoluteValue: Duration`

#### inMicroseconds

The value of this duration expressed as a Double number of microseconds.

`val inMicroseconds: Double`

#### inMilliseconds

The value of this duration expressed as a Double number of milliseconds.

`val inMilliseconds: Double`

#### inNanoseconds

The value of this duration expressed as a Double number of nanoseconds.

`val inNanoseconds: Double`

### Functions

#### div

#### isFinite

Returns true, if the duration value is finite.

`fun isFinite(): Boolean`

#### isInfinite

Returns true, if the duration value is infinite.

`fun isInfinite(): Boolean`

#### isNegative

Returns true, if the duration value is less than zero.

`fun isNegative(): Boolean`

#### isPositive

Returns true, if the duration value is greater than zero.

`fun isPositive(): Boolean`

#### toComponents

Splits this duration into days, hours, minutes, seconds, and nanoseconds and executes the given action with these components. The result of action is returned as the result of this function.

`fun <T> toComponents(`

action: (days: Int, hours: Int, minutes: Int, seconds: Int, nanoseconds: Int) -> T

): T

Splits this duration into hours, minutes, seconds, and nanoseconds and executes the given action with these components. The result of action is returned as the result of this function.

`fun <T> toComponents(`

action: (hours: Int, minutes: Int, seconds: Int, nanoseconds: Int) -> T

): T

#### toDouble

Returns the value of this duration expressed as a Double number of the specified unit.

`fun toDouble(unit: DurationUnit): Double`

#### toInt

Returns the value of this duration expressed as an Int number of the specified unit.

`fun toInt(unit: DurationUnit): Int`

#### toIsoString

Returns an ISO-8601 based string representation of this duration.

`fun toIsoString(): String`

#### toLong

Returns the value of this duration expressed as a Long number of the specified unit.

`fun toLong(unit: DurationUnit): Long`

#### toLongMilliseconds

Returns the value of this duration expressed as a Long number of milliseconds.

`fun toLongMilliseconds(): Long`

#### toLongNanoseconds

Returns the value of this duration expressed as a Long number of nanoseconds.

`fun toLongNanoseconds(): Long`

#### toString

Returns a string representation of this duration value expressed in the unit which yields the most compact and readable number value.

`fun toString(): String`

Returns a string representation of this duration value expressed in the given unit and formatted with the specified decimals number of digits after decimal point.

`fun toString(unit: DurationUnit, decimals: Int = 0): String`

#### unaryMinus

Returns the negative of this value.

`operator fun unaryMinus(): Duration`

### Companion Object Properties

### Companion Object Functions

#### convert

Converts the given time duration value expressed in the specified sourceUnit into the specified targetUnit.

`fun convert(`

value: Double,

sourceUnit: DurationUnit,

### Extension Functions

#### coerceAtLeast

Ensures that this value is not less than the specified minimumValue.

`fun <T : Comparable<T>> T.coerceAtLeast(minimumValue: T): T`

#### coerceAtMost

Ensures that this value is not greater than the specified maximumValue.

`fun <T : Comparable<T>> T.coerceAtMost(maximumValue: T): T`

#### coerceIn

Ensures that this value lies in the specified range minimumValue..maximumValue.

`fun <T : Comparable<T>> T.coerceIn(`

minimumValue: T?,

maximumValue: T?

): T

Ensures that this value lies in the specified range.

`fun <T : Comparable<T>> T.coerceIn(`

range: ClosedFloatingPointRange<T>
