iso8601 Duration parser and formatter

The current go native time pkg does not support any ISO 8601 duration strings.

This library provides the functionality to parse and format a native Go time.Duration to and from an ISO 8601-2 duration string.

What is still missing?

Currently, fast formatting (Format) does not support duration parts smaller than one second.

Installation

go get github.com/Achsion/iso8601/v2

will resolve and add the package to the current development module, along with its dependencies.

Usage

package main

import (
	"github.com/Achsion/iso8601"
)

func main() {
	// Quick parsing to go duration:
	duration, err := iso8601.ParseToDuration("P1Y1M1DT1H1M1.1S")

	// Slower, but more complete parsing to custom duration struct:
	isoDuration, err := iso8601.DurationFromString("P1Y1M1DT1H1M1.1S")
}
