如何在golang中转换ISO 8601时间？

What is the equivalent code in golang for the following shell command ? date -u +%Y-%m-%dT%T%z

package main

import (
    "time"
    "fmt"
)

func main(){
    fmt.Println(time.Now().Format(time.RFC3339))
}

golang Time.Format

package main

import (
    "fmt"
    "time"
)

func main() {
    fmt.Println(time.Now().UTC().Format("2006-01-02T15:04:05-0700"))
}

ISO8601 allows for variable levels of granularity. You can have just a year, year+month, year+month+day, add a time portion, and optionally have a timezone portion. Go's built-in time parsing, however, requires you to know ahead-of-time which parts will be included.

The github.com/btubbs/datetime library provides a more flexible parser that can handle all the commonly used ISO8601 formats. See https://github.com/btubbs/datetime

Disclosure: I wrote that library.

I had the following spec:

YYYY-MM-DDThh:mm:ss.sssZ

with the final Z being explicitly present in the examples.

Here's how I dealt with it: * first I found the time.RFCxxx that was the closest to my target * I copied its value * I fiddled with it until I found the expected result

which is
