Nanoduration

Duration type with nanosecond precision

Description

The type nanoduration is a length of time (implemented as an S4 class) with nanosecond precision. It is a count of nanoseconds and may be negative. The expected arithmetic operations are provided, including sequence generation.

Usage

nanoduration(hours, minutes, seconds, nanoseconds)

Arguments

Argument	Description
`hours`	number of hours
`minutes`	number of minutes
`seconds`	number of seconds
`nanoseconds`	number of nanoseconds
`x`	a `nanoduration` object
`object`	argument for method `show`
`quote`	indicates if the output of `print` should be quoted
`...`	further arguments passed to or from methods.
`e1`	Operand of class `nanoival`
`e2`	Operand of class `nanoival`
`na.rm`	if `TRUE` NA values are removed for the computation
`i`	index specifying elements to extract or replace.
`j`	Required for `[` signature but ignored here

`value`	argument for `nanoduration-class`

Format

An object of class nanoduration of length 1.

Details

A nanoduration can be constructed with the function as.nanoduration which can take the types integer64, integer and numeric (all indicating the count in nanosecond units) or the type character.

It can also be constructed by specifying with individual arguments the hours, minutes, seconds and nanoseconds with a call to nanoduration.

A nanoduration is displayed as hours, minutes, seconds and nanoseconds like this: 110:12:34.123_453_001. The nanosecond precision displayed is adjusted as necessary, so e.g. 1 second is displayed as 00:00:01.

Value

A nanoduration object

Examples

## constructors:
nanoduration(hours=10, minutes=3, seconds=2, nanoseconds=999999999)
as.nanoduration("10:03:02.999_999_999")
as.nanoduration(36182999999999)

## arithmetic:
as.nanoduration(10e9) - as.nanoduration(9e9)
as.nanoduration(10e9) + as.nanoduration(-9e9)
as.nanoduration("24:00:00") / 2
as.nanoduration("24:00:00") / as.nanoduration("12:00:00")

## comparison:
as.nanoduration("10:03:02.999_999_999") == 36182999999999
as.nanoduration("10:03:02.999_999_999") > as.nanoduration("10:03:02.999_999_998")
as.nanoduration("10:03:02.999_999_998") < "10:03:02.999_999_999"
