Golang : ISO8601 Duration Parser example



Tags : golang iso8601 duration-parser time

An example on how to parse ISO-8601 duration in string format and convert it to time.Duration type. However, this example doesn't parse M (month) because it cannot determine if the month is 29/30 or 31 days.

Here you go!

 package main

 import (
 "fmt"
 duration "github.com/channelmeter/iso8601duration"
 )

 func main() {

 // note : doesn't support month!
 // some months have 30 days and some 31/29 days!

 dura, err := duration.FromString("P1Y2DT3H4M5S") // dura is time.Duration type

 if err != nil {
 fmt.Println("Error : ", err)
 }

 fmt.Println("Duration : ", dura)

 fmt.Println("Year : ", dura.Years)
 fmt.Println("Day : ", dura.Days)
 fmt.Println("Hours : ", dura.Hours)
 fmt.Println("Minutes : ", dura.Minutes)
 fmt.Println("Seconds : ", dura.Seconds)
 fmt.Println("Weeks : ", dura.Weeks)
 fmt.Println("To duration : ", dura.ToDuration())

 fmt.Println("Has Time Part? : ", dura.HasTimePart())

 }

Sample output :

Year : 1

Day : 2

Hours : 3

Minutes : 4

Seconds : 5

Weeks : 0

To duration : 8811h4m5s

Has Time Part? : true
